Use the distributive property to evaluate the following expression : 3(x–7)
1. 3x-7
2. 3x-21
3. 3x+21

Use the distributive property to evaluate the following expression:
1/2 (4x+18)
1. 2x+9
2. 2x+36
3. 8x+36

Solve the one-step equation.
X–12= –9
X= ?

6=x + 15
X= ?

X/5=15
X= ?

–8y = 32
Y= ?

1/4x=7
X= ?

–18 + y= -5
Y=?

X/4= -7
Y=?
