What are the whole steps to get the answer for 4x -6=x +9?

x=5

Step-by-step explanation:

4x−6−x=x+9−x

3x−6=9

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
