Question

If 5x+3=10x-17, what is the value of x

Answer 1

4 = x

Explanation:

5x+3=10x-17

take away 5x from both sides

3 = 5x - 17

add 17 to both sides

20 = 5x

divide both sides by 5 to get x by itself

4 = x

Answer 2

x = 4

Explanation:

Step 1: Write equation

5x + 3 = 10x - 17

Step 2: Solve for x

1. Subtract 5x on both sides: 3 = 5x - 17
2. Add 17 to both sides: 20 = 5x
3. Divide both sides by 5: x = 4

Step 3: Check

Plug in x to verify it's a solution.

5(4) + 3 = 10(4) - 17

20 + 3 = 40 - 17

23 = 23
