Answer:
<h2>(-6, 312), (6, 312)</h2>
Step-by-step explanation:
I was doing it wrong. You have to find 30% of $86 which is $25.80, i think, and then take it away from $86 and so the sales price is $86 - $25.80 = $60.20. Originally I only did the first bit, I forgot you have to take it away. sorry hope this helps more now.
Answer:
x = 5
y = 7
Step-by-step explanation:
<em>Since they are both equal to </em><em>y</em><em>, we can set them equal to each other.</em>
2x - 3 = x + 2
<em>Combine like terms and isolate the </em><em>x</em><em>.</em>
x = 5
<em>Plug in the x to either equation to get the value of </em><em>y</em><em>.</em>
y = (5) + 2
y = 7
