Sample Problem

Question source

The solution to the equation is
(1) 8.3 (3) 3
(2) 8.7 (4) -3


1. Use the distributive property.
4(x-7)= 0.3(x+2) +2.11
4x-28= 0.3x+0.6 +2.11

2. Add 0.6 and 2.11.
4x-28= 0.3x+2.71

3. Subtract 0.3x on both sides.
4x-28= 0.3x+2.71
-0.3x -0.3x
3.7X-28= 2.71

4. Add 28 on both sides.
3.7x-28= 2.71
+28 +28
3.7x= 30.71

5. Divide 3.7 on both sides to isolate the x.
3.7x/3.7= 30.71/3.7
