Question 1:
<span>b + 8 = 13
b = 13 - 8
b = 5
Hence, the answer is A.
Question 2:
</span><span>3x – 2 = 3x + 5
3x - 3x -2 = 5
-2 </span>≠ 5
Hence, the answer is A.
Question 3:
<span>5q – 10 = 75
</span>
5q = 75 + 10
5q = 85
q =
q = 17
Hence, the answer is A.
Question 4:
<span>3(2t + 5) = 5t + 25
</span>
6t + 15 = 5t + 25
6t - 5t = 25 - 15
t = 10
Hence, the answer is C.
Question 5:
<span>6x – 2x – 5 = –6 + 21
4x = 15 + 5
4x = 20
x = </span>
x = 5
Hence, the answer is D.
Question 6:
<span>4x = 64
x = </span>
x = 16
Hence, Asher is wrong. You have to divide by 4 not subtract by 4.
Question 7:
<span>5(2x - 8) + 15 = -15
10x - 40 + 15 = -15
10x - 25 = - 15
10x = -15 + 25
10x = 10
x = </span>
x = 1
<span>b + 8 = 13
b = 13 - 8
b = 5
Hence, the answer is A.
Question 2:
</span><span>3x – 2 = 3x + 5
3x - 3x -2 = 5
-2 </span>≠ 5
Hence, the answer is A.
Question 3:
<span>5q – 10 = 75
</span>
5q = 75 + 10
5q = 85
q =
q = 17
Hence, the answer is A.
Question 4:
<span>3(2t + 5) = 5t + 25
</span>
6t + 15 = 5t + 25
6t - 5t = 25 - 15
t = 10
Hence, the answer is C.
Question 5:
