Question

Solve the system by graphing.

Answer 1

solve both equations for y then i will help

Answer 2

ok one minute

Answer 3

y = 2

Answer 4

-3x - y = -10
4x - 4y = 8
**********************
(-3x - y = -10)*4=-12x - 4y = -40
4x - 4y = 8
******************
-12x - 4y = -40
4x - 4y = 8
-----------------------subtract
(-12x - 4x) + (-4y - -4y) = (-40 - 8)
-16 x = -48
x = -48/-16 = 3

plug it in on of the equations and solve for y what do you get?

Answer 5

uh....

Answer 6
