Question

3 + 5x - 10 = 13, Whats x?

Answer 1

Hi there, 3+-10=-7 so, -7+5x=13. First, we add -7 to both sides, which gives us 5x=13+7, 13+7=20, so 5x=20. Now, we divide both sides by 5, Therefore, x=4

Answer 2

3+5x-10=13
Put all like terms together.
5x+3-10=13
5x-7=13
Subtract.
5x=20
Divide.
x=4

Hope this helps :)
