<span>3/4(4c+16)=2c+9
We simplify the equation to the form, which is simple to understand
<span>3/4(4c+16)=2c+9
Reorder the terms in parentheses
<span>+(+3c+12)=2c+9
Remove unnecessary parentheses
<span>+3c+12=+2c+9
We move all terms containing c to the left and all other terms to the right.
<span>+3c-2c=+9-12
We simplify left and right side of the equation.
<span>+1c=-3
We divide both sides of the equation by 1 to get c.
<span>c=-3
Hope this helped! :)
