Solve for x.
6(x – 1) = 9(x + 2)
2 answers:
First Reorder the terms: <span>-6 + 6x = 9(2 + x)
-6 + 6x = (2 * 9 + x * 9)
-6 + 6x = (18 + 9x).
</span><span>Move all terms containing x to the left, all other terms to the right.
</span>Add '-9x' to each side of the equation.
-6 + 6x + -9x = 18 + 9x + -9x
Combine like terms: 6x + -9x = -3x
-6 + -3x = 18 + 9x + -9x
<span>Combine like terms again =): 9x + -9x = 0
-6 + -3x = 18 + 0
-6 + -3x = 18
</span>Add '6' to each side of the equation.
-6 + 6 + -3x = 18 + 6
Combine like terms again....: -6 + 6 = 0
0 + -3x = 18 + 6
-3x = 18 + 6
Last time I promise! Combine like terms: 18 + 6 = 24<span>-3x = 24
</span>Divide each side by '-3'.
x = -8.
<span>x = -8
Happy studying ^-^
