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
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
