Help! ac{x}{3} +5=x-1" align="absmiddle" class="latex-formula">

Answer 1

$\frac{x}{3}+5=x-1$

Whenever there's a denominator. Multiply all whole equation with the denominator. For example, the denominator here in the equation is 3. So we multiply the whole equation by 3.

$\frac{x}{3}(3)+5(3)=x(3)-1(3)\\x+15=3x-3$

Moving the x to the same term which goes for the same as the constant for easier in solving.

$15+3=3x-x$

Moving to the another side, changing the sign/operator to opposite (From plus to minus, from multiply to divide.)

$18=2x\\2x=18$

Move 2 to another side, aka to divide 18.

$x=\frac{18}{2}\\x=9$

Therefore, the answer is x = 9.
