4.10 QUIZ Solving Equations with Integers

Answer 1

1. Solve for x: 3x - 7 = 11
Solution:
Add 7 to both sides: 3x = 18
Divide by 3: x = 6

2. Solve for y: 5y + 3 = -7
Solution:
Subtract 3 from both sides: 5y = -10
Divide by 5: y = -2

3. Solve for z: 2z - 4 = 10
Solution:
Add 4 to both sides: 2z = 14
Divide by 2: z = 7

4. Solve for a: 4a + 8 = -4
Solution:
Subtract 8 from both sides: 4a = -12
Divide by 4: a = -3

5. Solve for b: 9b - 5 = 31
Solution:
Add 5 to both sides: 9b = 36
Divide by 9: b = 4
