Read each question carefully and balance the equations by finding the value of the unknown variable. Show your work where indicated.
1. Solve for x: 3x + 7 = 22
2. Solve for x: 5x - 10 = 3x + 4
3. Solve for x: 2(x + 4) = 18
For the equation 4x - 5 = 15, the value of x is 5.
True
False
The equation 6 + y = 14 is balanced when y = 8.
True
False
1. To balance an equation, whatever operation you perform on one side, you must also perform on the side.
2. In the equation 2x + 5 = 11, the first step to isolate x is to 5 from both sides.
Consider a balance scale representing the equation x + 3 = 7. If one side has 'x' and three unit weights, and the other side has seven unit weights, what must 'x' be to keep the scale balanced?
1. Which operation would you use first to solve the equation x/4 - 2 = 6?
Multiply by 4
Add 2
Subtract 2
Divide by 4
