Answer:
simple. get a calculator and enter 12 x 89.92
Answer:
x=-3 and y= -6
Step-by-step explanation:
we have
6=-4x+y and -5x-y = 21
6+4x=y we substitute y in the second equation
-5x-(6+4x)=21
-9x-6=21
-9x=27
x=-3
we substiture x in the second
-5(-3)-y =21
15-y=21
15-21=y
y=-6
The solution is 2. -3+5=2
