Y = x -5<br> x + y = -1 <br> whats the soultion for the systeam of eqations

pantera1 [17]

Answer:

x = 2

y = -3

Step-by-step explanation:

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

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

Substitute y = x -5 in equation (II)

x + (x - 5) = -1

x + x - 5 = -1 {Combine like terms}

2x - 5 = -1 {Add 5 to both sides}

2x = -1 + 5

2x = 4 {Divide both sides by 2}

x = 4/2

x = 2

Substitute x = 2 in equation (I)

y = 2 - 5

y = -3
