1. Solving Linear Equations Josefina Zarazua 8th Grade Mathematics

2. Solve: 4x+13=21 • X=2 • X=4 • X=3 • None of these

3. Is 2 a solution for 2y+3y=12-y ? • Yes • No

4. Solve for x the given equation:8x-2(4-x)=14 X=3.66 X=2.2 X=1 X=2.34

5. Solve by clearing fractions¾ x + ½=2/3 X= 1/8 X= 2/9 X= 14/9 X= 7/8 3/4X+1/2=2/3 1/2X=4
