Answer:

x = 6 and y = 17

The solution is 6, 17

Explanation:

y = 2x + 5;y = 3x − 1

Step 1: Solve y = 2x + 5 for y:

y=2x+5

Step 2: Substitute 2x + 5 for y in y=3x−1:

y=3x−1

2x+5=3x−1

2x+5+−3x=3x−1+−3x(Add -3x to both sides)

−x+5=−1

−x+5+−5=−1+−5(Add -5 to both sides)

−x=−6

-x/-1 = -6/-1 (Divide both sides by -1)

x = 6

Step: Substitute 6 for x in y=2x+5:

y=2x+5

y=(2)(6)+5

y=17(Simplify both sides of the equation)

Answer:

x=6 and y=17
