Question

Solve the simultaneous equations
-x + 5y = -7
x + y = – 5
x = 1
y= 0

Answer 1

Answer:

y=-x-5

-x+5(-x-5)=-7

-x-5x-25=-7

-6x=18

x=-3

-(-3)+5y=-7

3+5y=-7

5y=-10

y=-2

solution

(-3,-2)

Hope This Helps!!!

Answer 2

Step-by-step explanation:

-x+5y= -7

x+y=-5

add both equation to eliminate x

6y=12 :. y=2

substitute y =2 in equation (2)

x +2 =. -5

x = -5+2 = -3

:. y=-2 ,x = -3
