Solving Linear Equations in One Variable

-3y = 105

(a)  

g - 7 = 10

(a)  

5 + b = 4

• -1

• -9

• 9

• 1

Answer explanation

To solve for b, subtract 5 from both sides of the equation: b = 4 - 5 = -1. Therefore, the correct answer is -1.

-7k = -21

(a)  

3d - 4 = 5

• 3

• 4

• 5

• 2

Answer explanation

To solve for d, add 4 to both sides of the equation: 3d = 9. Then, divide by 3 to find d = 3. Therefore, the correct answer is 3.

5 + 2w = 13

(a)  

5h - 2 = 3(h + 2)

(a)  

3e - 15 = 3

• 6

• -6

• 5

• -5

Answer explanation

To solve the equation, add 15 to both sides to isolate the variable: 3e = 18. Then, divide by 3 to find e = 6. Therefore, the correct answer is 6.

4(x + 4) - 2x = 12
