Given the set of equations:
2x + y = 10
y = 3x
Let's solve for x and y.
Here, let's use substitution method.
Substitute 3x for y in equation 1:
2x + y = 10
2x + 3x = 10
5x = 10
Divide both sides by 5:
In equation 2, substitute 2 for x to find y.
y = 3x
y = 3(2)
y = 6
Therefore, we have:
x = 2 and y = 6
ANSWER:
x = 2, y = 6
Answer:
1:4
Step-by-step explanation:
If 8/10 prefer Crest, that means 2/10 don't prefer it.
To find the ratio, put together the number that don't prefer it to the number that does:
2:8
Simplify by dividing each side by 2:
1:4
So, the ratio is 1:4

Answer:
D. Brandon is not correct because he should have added 6 negative unit tiles to isolate the variable in step 2
Step-by-step explanation:
Key goal is to have x on one side while the other value to the right. By subtracting 14x on both sides, you would get x+6=5. You would finally subtract 6 on both sides, not 5, to get the x by itself, thus x=-1.
