Answer: x = -8 ; y = -6
Step-by-step explanation:
1*x-2*y=4
1*x = 4 + 2*y
x = 4 + 2*y
Now you replace the value of x on the following equation:
-1*x+10*y=8
-1*(4 + 2*y) = 8
-4 - 2*y = 8
-2*y = 8+4
-2*y = 12
y = -12/2
y = -6
You replace the value of y in the previous equation:
x = 4 + 2*y
x = 4 + 2*(-6)
x = 4 - 12
x = -8

<span>
the answer is 3.75 I'll explain ,</span><span>here: 1.5 times 2 equals 3 now go to a different section and divide 1.5 by 2 then add the two together it will look kind of like this:</span>
<span>(1.5*2)+(1.5/2)=3.75</span>
