Question

Y=3x-19 5x+y=5 substitution

Answer 1

x = 3

y = -10

Explanation:

5x + y = 5 y = 3x - 19

5x + 3x - 19 = 5

8x - 19 = 5

8x = 24

x = 3

Now put x in to solve for y

y = 3(3) - 19

y = 9 - 19

y = -10

Let's check

5(3) - 10 = 5

15 - 10 = 5

5 = 5

So, x = 3 and y = -10 is the correct answer.
