Question

Can anyone please helping me out with question 3 it’s my last question and I can’t get it!!!

Answer 1

Answer:

x=1, y= -1

Step-by-step explanation:

x = 2y +3

3x -y = 4

Use the substitution method because we have x= something in terms of y

3 (2y+3) -y = 4

6y + 9 -y = 4 subtract 9 from both sides

6y -y = 4-9 combine like terms

5y = -5 divide both sides by 5

y = -1

x= 2*(-1) +3 = -2+3 = 1
