Answer:
x = -4
Step-by-step explanation:
y = 3x - 1
Replace all instances of Y into the second quation.
2x - (3x-1) = 5
2x -3x +1 = 5
-x = 4
x= -4
Answer:
z=2x+6xy factor out x
z=x(2+6y) get x by itself
z/(2+6y) = x
Step-by-step explanation:
4y-5=4x+7

Hello,
The sum of the angles or any triangle is always going to be 180°
So if the vertex angle is 40°, then each base angle is:
180 = 40 + 2x
x = (180 - 40) / 2
x = 70°
The answer is A.
Bye :-)
