Step-by-step explanation:
Answer:
Kevin can afford to have 15 guests at his party.
Step-by-step explanation:
You know that Kevin's party costs $52, so you can subtract 52 from 97, which is 45. So, he can spend $45 dollars on guests. $45 divided by 3, the amount it takes for each guest, to get 15.
Answer:
x = 1
Step-by-step explanation:
<u>Step 1: Choose one of the equations to solve for y:</u>
x - y + 1 = 0
(-y) / -1 = (-1 - x) / -1
y = 1 + x
<u>Step 2: Plug in y into either equation</u>
3x + 2(1 + x) = 7
3x + 2 + 2x - 2= 7 - 2
5x / 5 = 5 / 5
x = 1
Answer: x = 1
