x= -13 , y=11
Step-by-step explanation:
Using elimination method, make the x variable equal to eliminate the variable
-3x - y = -28
2x+ 3y=7
2(-3x-y =28)
3(2x+3y=7)
-6x - 2y =56
6x +9y=21
Apply addition
7y = 77
y=77/7 = 11
Use the value of y=11 in
2x+ 3y=7
2x +3(11) =7
2x +33 =7
2x=7-33
2x= -26
x= -26/2 = -13

Do up one over 3 and start at 0, that is what I recommend
X=2
-4 on both sides
4=2x
divide by 2 on both sides
X=2
First you have to solve the equation inside the parentheses. (5 + 3) = 8. Then you multiply,
6 • 8 = 48. After that just divide 48 by 2 and the answer is 24. Hope this helped.
