You want to get the x's on one side and all the other numbers on the other side of the equation.
2x-5x+6=0
2x-5x=-6
-3x=-6
x=2
It's 75. After you wrote down all the possibilities for what G could be, just find the one that has a combination of numbers that add up to 12. 75 is 7+5=12
Answer:
r+1
Step-by-step explanation:
-2x + 5y = 8
2x + 2y = 6
----------------add
7y = 14
y = 14/7
y = 2
2x + 2y = 6
2x + 2(2) = 6
2x + 4 = 6
2x = 6 - 4
2x = 2
x = 2/2
x = 1
solution is (1,2)
The triangle is equilateral
