8-9x=15x+7+3x
show how you get x

Simplify 15x + 7 + 3x to 18x + 7

8 - 9x = 18x + 7

Add 9x to both sides

8 = 18x + 7 + 9x

Simplify 18x + 7 + 9x to 27x to 7

8 = 27x + 7

Subtract 7 from both sides

8 - 7 = 27x

Simplify 8 - 7 to 1

1 = 27x

Divide both sides by 27

1/27 = x

Switch sides

x = 1/27

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
