Question

-4x + 5y = -11
2x + 3y = 11
When I solved I got (4,1)
Could someone show me how you solve and what you get.

Answer 1

try to eliminate one of the variables.... what happens if you multiply the bottom equation by 2 and then add it to the top equation?

Answer 2

Solve one equation for a variable.
2x+3y=11
2x=11-3y
x=(11-3y)/2
substitute into other equation
-4x+5y=-11
-4((11-3y)/2)+5y=-11
((-44+12y)/2)+5y=-11
-22+6y+5y=-11
11y=11
y=1
Now go back to any of the equations and substitute y=1 and solve for x
-4x+5y=-11
-4x+5(1)=-11
-4x=-16
x=16/4
x=4
so your answer is correct at (4, 1)

Answer 3

lol
2*(2x + 3y = 11) = 4x + 6y = 22
+ -4x + 5y = -11
----------------
11y =11
y=1
2x+3=11
2x=8
x=4
