Answer:
x=-4 and y=10
Step-by-step explanation:
Use the second equation to make y=x+6
sub y=x+6 into the first equation
-x-2*(x+6)=0
-x-2x-12=0
-3x-12=0
3x=-12
x=-4
Now sub x=-4 into the second equation
-(-4)+y=6
y=6+4
y=10
The answer is five remainder four
Answer:
x=64
Step-by-step explanation: because the sides are both the same so do 128/2 which equals 64 so x=64
