Solve for x
x=\frac{3\left(y-4\right)}{2}
Steps for Solving Linear Equation
y = \frac { 2 } { 3 } x + 4
Swap sides so that all variable terms are on the left hand side.
Swap sides so that all variable terms are on the left hand side.
\frac{2}{3}x+4=y
Subtract 4 from both sides.
Subtract from both sides.
\frac{2}{3}x=y-4
Divide both sides of the equation by \frac{2}{3}\approx 0.666666667, which is the same as multiplying both sides by the reciprocal of the fraction.
Divide both sides of the equation by , which is the same as multiplying both sides by the reciprocal of the fraction.
\frac{\frac{2}{3}x}{\frac{2}{3}}=\frac{y-4}{\frac{2}{3}}
Dividing by \frac{2}{3}\approx 0.666666667 undoes the multiplication by \frac{2}{3}\approx 0.666666667.
Dividing by undoes the multiplication by .
x=\frac{y-4}{\frac{2}{3}}
Divide y-4 by \frac{2}{3}\approx 0.666666667 by multiplying y-4 by the reciprocal of \frac{2}{3}\approx 0.666666667.
Divide by by multiplying by the reciprocal of .
x=\frac{3y}{2}-6
Solve for y
y=\frac{2\left(x+6\right)}{3}
Assign y
y≔\frac{2\left(x+6\right)}{3}
