D+7/-3 = 4

someone help me asap pls ill give you

d = -19

Step-by-step explanation:

= 4

You can move the (-3) to the other side.

d+7 = 4 × (-3)

d+7 = -12

Isolate d.

d = -12-7

Find d.

d = -19

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.
