<\/p>\nExercise 1:<\/p>\n
Solve each equation. Use both tape diagrams and algebraic methods for each problem. Use substitution to check your answers.<\/p>\n
a. b + 9 = 15
\nAnswer:
\n<\/p>\n
Algebraically:
\nb + 9 = 15
\nb + 9 – 9 = 15 – 9
\nb = 6
\nCheck:
\n6 + 9 – 9 = 15 – 9; 6 = 6. This is a true number sentence, so 6 is the correct solution.<\/p>\n

\nAnswer:
\n![\"Eureka](\"https:\/\/ccssanswers.com\/wp-content\/uploads\/2021\/04\/Eureka-Math-Grade-6-Module-4-Lesson-26-Problem-Set-Answer-Key-7.png\")
<\/p>\n
m is equal to 24; m = 24.
\nCheck:
\n24 – 7 = 17; 17 = 17. This number sentence is true, so the solution is correct.<\/p>\n
Question 2.
\nFind the solution of the equation below algebraically. Check your answer.
\nAnswer:
\nn + 14 = 25
\nn + 14 – 14 = 25 – 14
\nn = 11
\nCheck:
\n11 + 14 = 25; 25 = 25. This number sentence is true, so the solution is correct.<\/p>\n
Question 3.
\nFind the solution of the equation below using tape diagrams. Check your answer. p + 8 = 18
\nAnswer:
\n![\"Eureka](\"https:\/\/ccssanswers.com\/wp-content\/uploads\/2021\/04\/Eureka-Math-Grade-6-Module-4-Lesson-26-Problem-Set-Answer-Key-8.png\")
<\/p>\n
Check:
\n10 + 8 = 18; 18 = 18. This number sentence is true, so the solution is correct.<\/p>\n
Question 4.
\nFind the solution to the equation algebraically. Check your answer.
\nAnswer:
\ng – 62 = 14
\ng – 62 + 62 = 14 + 62
\ng = 76
\nCheck:
\n76 – 62 = 14; 14 = 14. This number sentence is true, so the solution is correct.<\/p>\n
Question 5.
\nFind the solution to the equation using the method of your choice. Check your answer. m + 108 = 243
\nAnswer:
\nTape Diagrams:<\/p>\n
![\"Eureka](\"https:\/\/ccssanswers.com\/wp-content\/uploads\/2021\/04\/Eureka-Math-Grade-6-Module-4-Lesson-26-Problem-Set-Answer-Key-9.png\")
<\/p>\n
Algebraically:
\nm + 108 = 243
\nm + 108 – 108 = 243 – 108
\nm = 35
\nCheck:
\n135 + 108 = 243; 243 = 243. This number sentence is true, so the solution is correct.<\/p>\n
Question 6.
\nIdentify the mistake in the problem below. Then, correct the mistake.
\nAnswer:
\np – 21 = 34
\np – 21 – 21 = 34 – 21
\np = 13
\nThe mistake is subtracting rather than adding 21. This is incorrect because p – 21 – 21 would not equal p.
\np – 21 = 34
\np – 21 + 21 = 34 + 21
\np = 55<\/p>\n
Question 7.
\nIdentify the mistake in the problem below. Then, correct the mistake.
\nAnswer:
\nq + 18 = 22
\nq + 18 – 18 = 22 + 18
\nq = 40
\nThe mistake is adding 18 on the right side of the equation instead of subtracting it from both sides.
\nq + 18 = 22
\nq + 18 – 18 = 22 – 18
\nq = 4<\/p>\n
Question 8.
\nMatch the equation with the correct solution on the right.
