Multiple Step Equations with Variables on Both Sides

Front

Isolating the variable term: Solve for x in the equation 4x + 7 = 2x + 15

Back

x = 4

Front

Solving for the variable: Solve for y in the equation 3(2y + 4) = 5y - 7

Back

y = -11

Front

Solving equations with variables on both sides: Solve for y in the equation 2y - 8 = 3y + 4

Back

y = -12

Front

Combining like terms: Simplify the expression 3x + 2y - 5x + 4y

Back

-2x + 6y
