Solve the equation
Solve for r
Solve for z
r=2−7+3zr=27+3z
Evaluate
∣3z−2r∣=7
Separate the equation into 2 possible cases
3z−2r=73z−2r=−7
Solve the equation for r
More Steps
Evaluate
3z−2r=7
Move the expression to the right-hand side and change its sign
−2r=7−3z
Change the signs on both sides of the equation
2r=−7+3z
Divide both sides
22r=2−7+3z
Divide the numbers
r=2−7+3z
