Imani spent half of her weekly allowance playing mini golf. to earn more money her parents let her wash the car for 4$. what is her weekly allowance if she ended up with 12$ explain how you got it -16$ -10.50 -8$ -12$

Her weekly allowance is x.

She spent half of the allowance, so she spent x/2 and had another x/2 left.

Then she earned $4. Now she has x/2 + 4.

She ended up with $12, so x/2 + 4 = 12

x/2 + 4 = 12

Subtract 4 from both sides.

x/2 = 8

Multiply both sides by 2.

x = 16

Her weekly allowance is $16.

answer: the answer is 23

step-by-step explanation:

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
