Answer: X- 4y - 12=0
step by step explanation:
First, move the constant to the left by adding its opposite to both sides
x-4y -12 = 12-12 =
X-4y-12 = 0
So the answer is X- 4y - 12=0
Answer:
x= 22
y = 35
Step-by-step explanation:
The base angles of a isosceles triangle are equal
3x-11 = 2x+11
Subtract 2x from each side
3x-2x -11 = 2x-2x+11
x-11 = 11
Add 11 to each side
x-11+11 = 11+11
x = 22
The sum of all the angles in a triangle is 180
3x -11 + 2x+11 + 2y = 180
Combine like terms
5x +2y = 180
5*22 + 2y = 180
110 + 2y = 180
Subtract 110 from each side
110+2y-110 = 180-110
2y = 70
Divide by 2
2y/2 =70/2
y = 35
Answer:
y=12
Step-by-step explanation:
This equation cannot be simplified further.
