2(-3x + 1) = 9x - 8
Simplify.
(2 · -3x) + (2 · 1) = 9x - 8
Simplify.
-6x + 2 = 9x - 8
Subtract 2 from both sides.
-6x = 9x - 8 - 2
Subtract 9x from both sides.
-6x - 9x = -8 - 2
Simplify.
-15x = -10
Divide both sides by -15.
x = 10/15
Simplify.
x = 2/3
Check your work! :)
To check your work, simply plug in 2/3 for x in our original equation.
2(-3x + 1) = 9x - 8
2{-3(2/3) + 1} = 9(2/3) - 8
Simplify.
2(-2 + 1) = 6 - 8
Simplify.
2(-1) = 6 - 8
Simplify.
-2 = -2
Therefore, x = 2/3
