Answer:
s = 6
Explanation:
Given: -2s + 8(9 - s) = 3 - (9 - 3s)
Get rid of the brackets by using the distributive property:
-2s + 72 - 8s = 3 - 9 + 3s
You can rearrange the items so the expression is easier to solve:
-2s - 8s + 72 = 3s + 3 - 9
Combine like terms:
-10s + 72 = 3s - 6
Now let's subtract 72 from both sides of the expression:
-10s = 3s - 78
Next, subtract 3s from both sides of the expression:
-13s = -78
Lastly, divide each side of the expression by -13 to get:
s = 6
