Question

how do you solve the equation 8x-5x=-27

Answer 1

x = -9

Answer 2

how do you get that?

Answer 3

so to solve a 1 variable equation (or any equation for that matter) you need to isolate the variable you are solving for, so in this case x.

first take 8x -5x and make that 3x using simple subtraction

next divide by 3 to get x alone

this leaves x = -9

Answer 4

8x-5x is the same as 3x.. so 3x=-27|||| THEN x=(-27/3)
