Question

Solve the following equations.

1.) 1/5x - 2 = -3
2.) 15 = 10 - x/4
3.) x/3 - 12 = -2
4.) x/-2 + (-6) = 6​

Answer 1

1. -5
2. -20
3. 30
4. -24

Explanation:

Solve the following equations.

1.) 1/5x - 2 = -3

2.) 15 = 10 - x/4

3.) x/3 - 12 = -2

4.) x/-2 + (-6) = 6​

1/5x - 2 = -3

1/5x = -1

x = -1 : 1/5

x = -1 × 5

x = -5

15 = 10 - x/4

5 = -x/4

x = -5 : 1/4

x = -5 × 4

x = -20

x/3 - 12 = -2

x/3 = 10

x = 10 × 3

x = 30

x/-2 + (-6) = 6​

x/-2 - 6 = 6

x/-2 = 12

x = -24
