Step-by-step explanation:
Step 1 - Expand the brackets out:
-8(x-3)
-8 * x = -8x
-8 * -3 = 24 (two negatives make a positive)
-8x + 24 = -32
Step 2 - Add 8x to both sides:
-8x + 24 + 8x = -32 + 8x
24 = -32 + 8x
Step 3 - Add 32 to both sides:
24 + 32 = -32 + 32 + 8x
56 = 8x
Step 4 - Divide both sides by 8:
56 ÷ 8 = 8x ÷ 8
7 = x
∴ proved.
Hope this helps!
