GIVING BRAINLIEST!!!!!!!!!!I NEED HELP
lapo4ka [179]
Answer: (-20,-4)

First, you substitute y into the first equation to get 0.01x - 0.3(0.1x - 2) = 1

You then distribute the 0.3 to what is inside the parentheses to get 0.01x-0.03x+0.6=1
(Note: the 0.6 is positive because two negatives multiplied equal a positive)

Now you combine like terms to get -0.02x+0.6=1

Subtract 0.6 from both sides of the equal sign to get -0.02x=0.4

Divide each side by -0.02 to get x=-20

Now plug in -20 to y=0.1x-2 to get y=-4

This gives you the answer (-20,-4)
