4.5 (8-x) + 36=102-2.5 (3x+24)

what's x?

First, group your like terms:

30-4.5x+36=102-7.5x-60

30+36-4.5x=102-60-7.5x

66-4.5x=42-7.5x

Second, add 7.5x on both sides:

66+3x=42

Next, subract 66 on both sides:

3x=-24

Now, divide 3 on both sides:

-24/3=-8

x=-8

Let's solve your equation step-by-step. 4.5 (8-x) + 36 = 102 - 2.5 (3x+24) Step 1: Simplify both sides of the equation. 4.5 (8-x) + 36 = 102 - 2.5 (3x+24) Simplify: (Show steps) - 4.5x + 72 = - 7.5x + 42 Step 2: Add 7.5x to both sides. - 4.5x + 72 + 7.5x = - 7.5x + 42 + 7.5x 3x+72 = 42 Step 3: Subtract 72 from both sides. 3x+72 - 72 = 42-72 3x=-30 Step 4: Divide both sides by 3. 3x3 = - 303 x = - 10
