Question

12*(32-(36+8x):5)=144

Answer 1

12×(32-(36+8x):5)=144
32-(36+8x):5=144:12=12
(36+8x):5=32-12=20
36+8x=20×5=100
8x=100-36=64
x=64:8=8

12×(32-(36+8×8):5)=144
144=144

Answer 2

To solve the given equation:

12 * (32 - (36 + 8x) / 5) = 144

Let's break down the steps to solve it:

Step 1: Simplify the expression inside the parentheses. 36 + 8x = 36 + 8x

Step 2: Perform the division inside the parentheses. 32 - (36 + 8x) / 5 = 32 - (36/5 + 8x/5) = 32 - (7.2 + 1.6x)

Step 3: Simplify the expression further. 32 - (7.2 + 1.6x) = 32 - 7.2 - 1.6x = 24.8 - 1.6x

Step 4: Substitute the simplified expression back into the original equation. 12 * (24.8 - 1.6x) = 144

Step 5: Distribute the multiplication. 297.6 - 19.2x = 144

Step 6: Move all terms to one side to set the equation to zero. 297.6 - 19.2x - 144 = 0

Step 7: Combine like terms. 153.6 - 19.2x = 0

Step 8: Move the constant term to the other side. -19.2x = -153.6

Step 9: Divide both sides by -19.2 to solve for x. x = (-153.6) / (-19.2) x = 8

Therefore, the solution to the equation is x = 8.
