Answer:

-1 -y/5

Explanation:

-5x + y = 1

Subtract yy from both sides.

-5x=1-y

−5x=1−y

2 Divide both sides by -5−5.

x=-\frac{1-y}{5}

x=−

5

1−y

-10x+2y=-2

Factor out the common term 22.

2(5x+y)=-2

2(5x+y)=−2

2 Divide both sides by 22.

5x+y=-1

5x+y=−1

3 Subtract yy from both sides.

5x=-1-y

5x=−1−y

4 Divide both sides by 55.

x=\frac{-1-y}{5}

x=

5

−1−y
