Question

What does X =?
What does Y =?

Answer 1

X = 5

Y = 2

Explanation:

Answer 2

`\huge\boxed{x = 5, y =-2 }`

Explanation:

Given equations:

3x + 5y = 5 ------------(1)

7x + 5y = 25 ----------(2)

• Subtract Eq. (2) from (1)

3x + 5y - (7x + 5y) = 5 - 25

3x + 5y - 7x - 5y = -20

• Cancel 5y

3x - 7x = -20

-4x = -20

• Divide both sides by -4

x = -20/-4

x = 5

• Put x = 5 in Eq. (1)

3(5) + 5y = 5

15 + 5y = 5

• Subtract 15 from both sides

5y = 5 - 15

5y = -10

• Divide both sides by 5

y = -10/5

y = -2
