That is easy!! :)
y=3 and x=-7
When you find the factors of something like this, you have to just get the letter alone.
For example: y-3. You have to first write it as y-3=0, then you add 3 from BOTH sides of the = so that you can make the -3 go away and y will be alone. So, it will look like this: y-3+3=0+3. Then, you solve it for y (which just means that you want y by itself on one side of the = ). So, -3+3=0, which means they disappear from that side; since 0+3=3, that's what that side turns into, so what you end up with is y=3
Same thing goes for the x+7 equation:
x+7=0
x+7-7=0-7
x=-7
Step-by-step explanation:
61 + 90 = 151 degree
180 - 151 = 29 degree
180 - 29 = 151 degree is x value

Answer:
Step-by-step explanation:
Small order of fries at Wendy’s = x calories
Small order of fries at McDonald’s = y calories
<u>Substitute x in the second equation</u>
- y + 90 + y = 550
- 2y = 550 - 90
- 2y = 460
- y = 230
<u>Then, x is:</u>
- x = 230 + 90 = 320 calories
