Answer: -10x+7.5
Step-by-step explanation:
First multiply -2.5(4x)= -10x and then -2.5x-3= 7.5 it should be -10x+7.5
2x-y=32
y-5x=13
transform the second equation to make the elimination possible
2x-y=32
-5x+y=13
now, our ys match, and we can drop them out
2x-y=32
+
<u>-5x+y=13
</u> -3x+0=45
<u>x= -15
</u>
Now we use the meaning of x in one of the original equations
2*(-15)-y=32
-y=32+30
y=-62
The answer is (-15;-62)
