Solve one-step linear equations
Key Notes :
To solve for a variable, use inverse operations to undo the operations in the equation. Be sure to do the same operation to both sides of the equation.
Learn with an example
Solve for u.
4u = 11.84
u = _______
Solve.
4u = 11.84
4u/4 = 11.84/4 Divide both sides by 4
u = 2.96 simplify
Solve for q.
q/3=4
q =_______
Solve.
q/3= 4
q/3 . 3= 4 · 3 Multiply both sides by 3
q = 12 Simplify
Solve for q.
q + 1.96 = 8.46
q = _______
Solve.
q + 1.96 = 8.46
q + 1.96 − 1.96 = 8.46 − 1.96 Subtract 1.96 from both sides
q = 6.5 Simplify
