### 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, $w = 7$
