Please help me please i really need help please

Answer 1

Explanation:

x + y = 1 -------------------(I)

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

Multiply (I) by (-5) -5x - 5y = -5

5x + 3y = -3 {Now add}

-2y = -8

y = -8/-2

y = 4

Plugin y = 4 in equation (I)

x + 4 = 1

x = 1 -4

x = -3

Solution: (-3, 4)
