y = 3x + 2

Step-by-step explanation:

Mathematics

Find the solution to the system of equations shown below. 4y+12x=10 2y-6x= -8 a. no solution b. x= -6, y=2 c. x=13/12, y= -3/4 d. more than 1 solution

Step-by-step answer

P Answered by Master

4y+12x=10(1)
2y-6x= -8(2)

(1)+2(2)

4y+12x=10
4y-12x= -16

8y = -6
y= -6/8
y= -3/4

y in (2)
2y-6x= -8
2(-3/4)-6x= -8
-3/2-6x= -8
-3/2+8=6x
13/2=6x
(13/2)/6=x
13/12=x
x=13/12

C

I hope it helps you :)
