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
You would multiply -2 by 11 and get -22. Next your equation would equal to -22+9y=5. You simply subtract -22 from both sides, which basically means you're adding 22. Next your equation would be 9y=27. All that is left to do is divide both sides by 9, and you get that y is equal to 3.
