Question

What is 3x+7x=9-18? Math is confusing once you get into 7th grade.

Answer 1

x = -0.9

Explanation:

3x+7x=9-18

10x = -9

x = -9 / 10

x = -0.9

Answer 2

x-(-0.9)

Explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation::3*x+7*x-(9-18)=0

Solve::10x+9 = 0

Subtract 9 from both sides of the equation::10x = -9

Divide both sides of the equation by 10::x = -9/10 = -0.900
