1. Simplify the expression. 2 x (8 − 3) − 6

2. Solve the equation for c. 14c -6 = 22

3. What value of x makes this equation true? 2x + 18 = 5x

4. Simplify. 18 − c + 9c + 6

5. Solve for x. 8x=-56

1. [tex]2\cdot(8-3)-6=2\cdot5-6=4[/tex]

2. [tex]14c-6=22\implies14c=28\implies c=2[/tex]

3. [tex]2x+18=5x\implies 3x=18\implies x=6[/tex]

4. [tex]18-c+9c+6=24+8c[/tex]

5. [tex]8x=-56\implies x=-7[/tex]

Hope this helps :)
