Question

Whats the answer im confused

Answer 1

(-2,3)

Explanation:

y=x+5 y=−2x−1

Solve y=x+5 for y:

Substitute x+5 for y in y=−2x−1:

y=−2x−1

x+5=−2x−1

x+5+2x=−2x−1+2x (Add 2x to both sides)

3x+5=−1

3x+5+(−5)=−1+(−5) (Add -5 to both sides)

3x=−6

3x = -6 (Divide both sides by 3)

3 3

x=−2

Substitute −2 for x in y=x+5:

y=x+5

y=−2+5

y=3 (Simplify both sides of the equation)

Therefore, x= -2 and y=3
