  1. Solve the following equations for x. Homework Help ✎

    1. 4x − 6y = 20

    2. 12-6b

    3. 12-6c

    4. 12-6d

Add 6y to both sides and solve for x.

x = 5 + 1.5y

Multiply both sides by 2 first.

Subtract 3 from both sides and thensquare both sides to remove the square root. Solve for x.
