Solve the system of equations 2y-3x=-27 5y+3x=6 x= y=

Step-by-step explanation:

2y-3x=-27

5y+3x=6

You have to add both thee equations, this way the -3x and +3x will cancel out. So add going straight down.

(2y+5y)+(-3x+3x)=(-27+6)

7y=-21

y=-3

And from here plug in y=3 into any of the two original equations

So I picked 2y-3x=-27

2(-3) -3x=-27

-6-3x=-27

-3x=-27+6

-3x=-21

x=7

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
