Question

Solve for x: 7x + 3 =2x +13

Answer 1

Step-by-step explanation:

$7x+3=2x+13\\7x-2x=13-3\\5x=10\\x=2$

Answer 2

Answer:

x = 2

Step-by-step explanation:

7x + 3 = 2x + 13

Get all the x on the same side: 7x - 2x = 13 - 3

Subtract: 5x = 10

Divide both sides by 5 to get x = 2.

Plug the found value of x back in to check the answer: 7(2) + 3 = 2(2) + 13

Multiply: 14 + 3 = 4 + 13

Add: 17 = 17

This verifies that x = 2.
