Substitute x=6y-7 4x+y=-3

x = -1

y = 1

Step-by-step explanation:

x = 6y - 7

4x + y = -3

substitute x for 6y - 7 in the second equation

4x + y = - 3

4(6y - 7) + y = -3

open the parenthesis

24y - 28 + y = -3

combine like terms

25y - 28 = -3

add 28 to both sides of the equation

25y - 28 + 28 = -3 + 28

25y = -3 + 28

25y = 25

y = 1

now that you know y is 1, substitute it back into either equation

x = 6y - 7

x = 6 * 1 - 7

x = 6 - 7

x = -1
