Use the substitution method to solve the given system of equations. Write your answer as an ordered pair, (x, y).
y - x = 4
6y + 2x = 4
Please help I can’t get any wrong

(-5/2 , 3/2)

Step-by-step explanation:

y=4+x

6(4+x) + 2x= 4

24 + 6x + 2x= 4

24 + 8x= 4

8x =4 - 24

8x=-20

x= -20/8= -5/2

y-(-5/2)=4

y+5/2= 4

multiply throughout by 2 to clear out fraction

2y + 5= 8

2y= 8-5

2y=3

y=3/2

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
