Solve the linear equation by using substitution x-y=-4 3x-y=-10

(-3, 1)

Step-by-step explanation:

x-y=-4

3x-y=-10

y=x-(-4)=x+4

3x-(x+4)=-10

3x-x-4=-10

2x-4=-10

2x=-10+4

2x=-6

x=-6/2

x=-3

-3-y=-4

y=-3-(-4)=-3+4=1

x=-3, y=1. (-3, 1).

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
