Please help me, I'm doing a test.
Tju [1.3M]

Answer:

(3,4)

Step-by-step explanation:

first you're going to solve the equation -2x

your equation should now be: \left \{ {{-2x+3y\\=6} \atop {-2x=2-2y}} \right.

next you're going to substitute the given value of -2x into the equation -2x+3y=6

so your equation should now be: 2-2y+3y=6

next you're going to solve the equation for y

equation should now be: y=4

than you're going to substitute the given value of y into the equation -2x=2-2×4

then you're going to solve the equation for x

your equation should now be: x=3

then the possible solution of the system is the order pair: (x,y)=(3,4)
