    Answer: 5x + 4z = 10z - 2x

    move variable to the left side and change its sign

    5x + 2x + 4z + 10

    Move variable to the right side and change its sign. 5x + 2x = 10z - 4z Collect the like terms 5x + 2x = 10z - 4z ↓ 7x = 10z - 4z Collect the like terms ↓ 7x = 6z Divide both sides of the equation by 7 x = 6/7 z decimal 0.857143
