Question 1103262
1) -2x-2y=−4
:
2)  4x+3y=11
:
multiply equation 1 by 2
:
3) -4x -4y = -8
:
add equation 3 to equation 2
:
-y = 3
:
y = -3
:
substitute for y in equation 1
:
-2x -2(-3) = -4
:
-2x +6 = -4
:
-2x = -10
:
x = 5
:
********************************************
x = 5 and y = -3
:
substitute for x and y in equation 2
:
4(5) +3(-3) = 11
:
20 -9 = 11
:
11 = 11
:
our answer checks
