Question

X + y = 95. and y is 2/3 of x. find x and y.​

Answer 1

x=57

y=38

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

Answer 2

{x,y}={60,35}

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
