If the fraction 396/x-10 is equivalent to -22, find the value of x.

x = -8

Step-by-step explanation:

1. Miltiply x-10 on both sides: 396 = -22(x - 10)

2. Distribute -22 to (x - 10): 396 = -22x + 220

3. Subtract 220 from 396: 176 = -22x

4. Divide both sides by -22 to get x by itself: x = -8

I hope this is helpful :)

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
