How to solve y= -5x-8, y=3x-24

x=2 and y=−18

Step-by-step explanation:

Let's solve the system by substitution.

y=−5x−8;y=3x−24

Step: Solve y=−5x−8 for y:

y=−5x−8

Step: Substitute−5x−8 for y in y=3x−24:

y=3x−24

−5x−8=3x−24

−5x−8+−3x=3x−24+−3x(Add -3x to both sides)

−8x−8=−24

−8x−8+8=−24+8(Add 8 to both sides)

−8x=−16

−8x/−8=−16/−8

(Divide both sides by -8)

x=2

Step: Substitute 2 for x in y=−5x−8:

y=−5x−8

y=(−5)(2)−8

y=−18 (Simplify both sides of the equation)

answer: the first one
