Question 537103
Solve:
{{{12y+7 = 21y}}} First, collect the y's on one side of the equation by subtracting 12y from both sides.
{{{12y-12y+7 = 21y-12y}}} Evaluate this.
{{{7 = 9y}}} Now divide both sides by 9 to get the y by itself.
{{{7/9 = cross(9)y/cross(9)}}} Cancel the 9's on the right side.
{{{7/9 = y}}} or {{{highlight(y = 7/9)}}}
