Solve for x:

1.

4x - 7 = 3

Add 7 to both sides

4x = 10

Divide both sides by 4

x = 10/4

Simplify:

x = 5/2

Answer for question 1: x = 5/2

2.

13 + 2x/3 = 15

Multiply both sides by 3

39 + 2x = 45

Subtract 39 from both sides

2x = 6

Divide both sides by 2

x = 3

Answer for question 2: x = 3

3.

10x + 7 = 15

Subtract 7 from both sides

10x = 8

Divide both sides by 10

x = 8/10

Simplify

x = 4/5

Answer for question 3: x = 4/5

Step-by-step explanation:

We have to find the value of x.

1.) 4x - 7 = 3

  • Add the like terms

4x = 3 + 7

  • Subtract 7 from each section

4x - 7 = 3

4x = 3 + 7

4x = 10

x = 10/4

x = 5/2

2.) 13 + 2x/3 = 15

(39 + 2x)/3 = 15

39 + 2x = 15 × 3

39 + 2x = 45

  • Subtract 45 from each term.

39 - 45 + 2x = 45 - 45

- 6 + 2x = 0

2x = 6

x = 6/2

x = 3

3.) 10x + 7 = 15

Subtract 15 from each terms

10x + 7 - 15 = 15 - 15

10x - 8 = 0

10x = 8

x = 8/10

x = 4/5
