answer: [tex]x = 18[/tex]
work:
[tex]\frac{1}{3}x + 12 = 18[/tex] | subtract 12 on both sides, and solve.
[tex]\frac{1}{3}x = 6[/tex] | divide by [tex]\frac{1}{3}[/tex] on both sides, and solve.
[tex]x = 18[/tex] | final answer.
hope this helps! ❤ from peachimin
we need to isolate x, so we subtract 12 from both sides
then we get: x/3=6
so now we need to get x alone, so we would multiply each side my 3
now we would get x=18!
