Question

Systems -6=3x-6y, 4x=4+5y

Answer 1

-6=3x-6y, 4x=4+5y

Re order the equations

3x+6y=6

4x-5y=4

Multiply each equation by the value that makes the coefficients of xopposite and simplify.

4(-3x)+4(6y)= 4(6)

3(4x)+3(-5y=3(4)

You have two new equations Solve for y

-12x+24y=24

12x-15y=12

__________

9y = 36

Y= 36/9

Y = 4

Now substitute y in one of the equations to get x .

4x=4+5y

4x= 4+ 5(4)

4x= 4+ 20

4x= 24

X= 24/4

X= 6

So your answer is

X= 6

Y= 4

Point form (6,4)

Answer 2

x=6

y=4
