Answer:
{x,y}={60,35}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = y + 25
// Plug this in for variable x in equation [1]
[1] (y +25) + y = 95
[1] 2y = 70
// Solve equation [1] for the variable y
[1] 2y = 70
[1] y = 35
// By now we know this much :
x = y+25
y = 35
// Use the y value to solve for x
x = (35)+25 = 60
Answer:
x=57
y=38
Step-by-step explanation:
(1): x+y=95
(2): y=2/3x
substitute y=(2/3)x in equation (1):
x+(2/3)x=95
Multiply both sides by 3
3x+2x=285
5x=285
Divide both sides by 5
x=285/5
x=57
substitute x=57 in equation (2):
y=2/3×57=38
hence: x=57 , y=38
