Answer:
5y + 2y - 4x + 4x = -7 +14
7y = 7
y = 1
2(1) + 4x = 14
4x = 12
x = 3
Step-by-step explanation:
Using the process of elimination
Add both equations. The 4x will be eliminated since one is positive and one is negative. The equation is left with only the y variable and the constant.
When y is found, input it into the second equation to find x.
Hello!
For this one, all of them look like you can use mental math, but maybe choose the two middle ones and the bottom right one.
Hope this helps :))
Equilateral, because the sides are equal
Y=-x+9 is the correct answer
