Simplifying
37 + 8x = 4(7 + -1x)
37 + 8x = (7 * 4 + -1x * 4)
37 + 8x = (28 + -4x)
Solving
37 + 8x = 28 + -4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
37 + 8x + 4x = 28 + -4x + 4x
Combine like terms: 8x + 4x = 12x
37 + 12x = 28 + -4x + 4x
Combine like terms: -4x + 4x = 0
37 + 12x = 28 + 0
37 + 12x = 28
Add '-37' to each side of the equation.
37 + -37 + 12x = 28 + -37
Combine like terms: 37 + -37 = 0
0 + 12x = 28 + -37
12x = 28 + -37
Combine like terms: 28 + -37 = -9
12x = -9
Divide each side by '12'.
x = -0.75
Simplifying
x = -0.75

Step-by-step explanation:
ur welcome
Begin by multiplying $15.65 by 0.20 to find what 20% of the regular price is. This gives you 3.13, which in this situation means $3.13.
To find the price with discount subtract 15.65-3.13. This gives you $12.52.
To find out the change, subtract 20-12.52. This gives you $7.48.
So, he will receive $7.48 in change.
Hope this helps!
