Answer:

x = -4

y = 4

Step-by-step explanation:

Subtract the two equations

be sure to take the minus sign through the whole bottom equation

the 6y's will cancel and you are left with 3x = -12 or x =-4

Then take the x= -4 and plug it back into the top equation to get y = 4

Answer:

(x,y) = (-4,4)

Step-by-step explanation:

7x + 6y = -4

6y = 8 - 4x

substitute the value of 6y into the equation

--------------------------

7x + 8 - 4x = -4

Solve

---------------------------

x = -4

substitute the value of x into the equation

---------------------------

6y = 8 - 4(-4)

solve

----------------------------

y = 4

therefore,

----------------------------

(x,y) = (-4,4)
