2x+3y=5x−y Complete the missing value in the solution to the equation.

Step-by-step explanation:

Given simple equation:

2x+3y = 5x-y

and y = 0,

Substitute y = 0 in the equation, we get

=> 2x + 3×0 = 5x - 0

=> 2x = 5x

=> 0 = 5x - 2x

=> 3x = 0

=> x = 0

Therefore,

(x , y ) = ( 0, 0 )

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.
