Answer : B
Explanation
Step 1:
Given $43 = 7 + 4b$
Subtracting 7 from both sides
$43 −7 = 7 + 4b − 7; \: 36 = 4b$
Step 2:
Dividing both sides by 4
$\frac{36}{4} = \frac{4b}{4}$
So, $b = 9$
Answer : C
Explanation
Step 1:
Given $2w + 21 = 9w$
Subtracting 2w from both sides
$2w + 21 −2w = 9w − 2w; \: 21 = 7w$
Step 2:
Dividing both sides by 7
$\frac{21}{7} = \frac{7w}{7}$
So, $w = 3$
Answer : D
Explanation
Step 1:
Given $39 = 4s + 3$
Subtracting 3 from both sides
$39 − 3 = 4s + 3 − 3; \: 36 = 4s$
Step 2:
Dividing both sides by 4
$\frac{36}{4} = \frac{4s}{4}$
So, $9 = s$
Answer : A
Explanation
Step 1:
Given $20 = − 12 + 8x$
Adding 12 to both sides
$20 + 12 = − 12 + 8x + 12; \: 32 = 8x$
Step 2:
Dividing both sides by 8
$\frac{32}{8} = \frac{8x}{8}$
So, $4 = x$
Answer : C
Explanation
Step 1:
Given $2p + 8 = 22$
Subtracting 8 from both sides
$2p + 8 − 8 = 22 − 8; \: 2p = 14$
Step 2:
Dividing both sides by 2
$\frac{2p}{2} = \frac{14}{2}$
So, $p = 7$
Answer : B
Explanation
Step 1:
Given $5h + 2 = 42$
Subtracting 2 from both sides
$5h + 2 −2 = 42 −2; \: 5h = 40$
Step 2:
Dividing both sides by 5
$\frac{5h}{5} = \frac{40}{5}$
So, $h = 8$
Answer : A
Explanation
Step 1:
Given $− 25 = − 3 + 11y$
Adding 3 to both sides
$− 25 + 3 = − 3 + 3 + 11y; \: −22 = 11y$
Step 2:
Dividing both sides by 11
$\frac{−22}{11} = \frac{11y}{11}$
So, $y = −2$
Answer : D
Explanation
Step 1:
Given $11p + 5 = 49$
Subtracting 5 from both sides
$11p + 5 −5 = 49 −5; \: 11p = 44$
Step 2:
Dividing both sides by 11
$\frac{11p}{11} = \frac{44}{11}$
So, $p = 4$
Answer : B
Explanation
Step 1:
Given $47 = 2 + 5c$
Subtracting 2 from both sides
$47 − 2 = 2 + 5c −2; \: 45 = 5c$
Step 2:
Dividing both sides by 5
$\frac{5c}{5} = \frac{45}{5}$
So, $c = 9$
Answer : C
Explanation
Step 1:
Given $\frac{w}{7} − 15 = −14$
Adding 15 to both sides
$\frac{w}{7} − 15 + 15 = −14 + 15; \: \frac{w}{7} = 1$
Step 2:
Multiplying both sides by 7
$\frac{w}{7} \times 7 = 1 \times 7 = 7$
So, $w = 7$
