this is correct btw
The answer is:
Solve for y in the first equation
y=−5<span>
y=8−<span>x
</span></span>
<span>Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is <span>−5</span></span><span>y=−5</span><span><span>(−5)</span>=8−<span>x
</span></span>
Remove parentheses.<span>y=−5</span><span>−5=8−<span>x
</span></span>
Solve for x in the second equation.<span>y=−5</span>
<span>x=13</span>
The answer is <span>(13,−5<span>) Please mark as Brainliest

Let candy bars =xLet drinks =y Set up the two equations. 60x + 110y = 265120x + 90y = 270 Solve through elimination. Multiple the first equation by 2 and subtract the second equation from the first. When we multiply the first equation by two, we get: 2(60x +110y = 265) = 120x + 220y = 530 Then, when we subtract the second from the first we get: (120x + 220y = 530) - (120x +90y = 270) The result is 130y = 260 So, y=2 Then, we plug that back in to the original equation to find x. 60x + 220 = 265 Subtract 220 from both sides. 60x = 45 x = .75 So, drinks cost 2 dollars and candy bars cost 75 cents.
Hope this helps! :)
