Answer:
x = -5
Step-by-step explanation:
-2x + 8 = 18
Subtract 8 from each side
-2x + 8-8 = 18-8
-2x = 10
Divide each side by -2
-2x/-2 = 10/-2
Step 1: Write equation
Step 2: Solve for <em>x</em>
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-2(-5) + 8 = 18
10 + 8 = 18
18 = 18

a) a *5+5= 20
5a + 5 = 20
5a = 20 - 5
5a = 15
a = 15/5
a = 3
b) b/5 - 5 = 4
b/5 = 4 + 5
b/5 = 9
b =9*5
b = 45
