Answer:
You need to simplify 0.3(12x + -16) = 0.4(12 + -3x)
Step-by-step explanation:
Reorder the terms:
0.3(-16 + 12x) = 0.4(12 + -3x) (-16 * 0.3 + 12x * 0.3) = 0.4(12 + -3x) (-4.8 + 3.6x) = 0.4(12 + -3x) -4.8 + 3.6x = (12 * 0.4 + -3x * 0.4) -4.8 + 3.6x = (4.8 + -1.2x)
Solving -4.8 + 3.6x = 4.8 + -1.2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1.2x' to each side of the equation. -4.8 + 3.6x + 1.2x = 4.8 + -1.2x + 1.2x
Combine like terms: 3.6x + 1.2x = 4.8x -4.8 + 4.8x = 4.8 + -1.2x + 1.2x
Combine like terms: -1.2x + 1.2x = 0.0 -4.8 + 4.8x = 4.8 + 0.0 -4.8 + 4.8x = 4.8 Add '4.8' to each side of the equation. -4.8 + 4.8 + 4.8x = 4.8 + 4.8
Combine like terms: -4.8 + 4.8 = 0.0 0.0 + 4.8x = 4.8 + 4.8 4.8x = 4.8 + 4.8
Combine like terms: 4.8 + 4.8 = 9.6 4.8x = 9.6 Divide each side by '4.8'. x = 2
Simplifying x = 2

Answer:
50%
Step-by-step explanation:
if 32% play neither then you want to subtract 120 - 32 after you do that you want to add 25 + 13 to get the answer of 38 people who play cricket after you do that you want to subtract 88 - 38 because when you subtracted 120 - 32 you got the number of 88 after you subtract 88 - 38 you should get the number 50% I really hope that helped
