y + (2x -12) = 180 (since they are supplementary angles)
(2x-12) = 96 ( since they are alternate exterior angle)
2x = 96 + 12
2x = 108
x = 108/2
x = 54.
y+( 2x-12)=180
y+(2× 54 -12) = 180
y + (108-12) = 180
y + 96 = 180
y= 180-96
y = 84.

Answer:
What are we finding for X?
Step-by-step explanation:
Answer:
x = 53
Step-by-step explanation:
22 - 3 ( x - 70 ) = x + 20 Multiply out
22 - 3x + 210 = x + 20
22 + 210 - 3x = x + 20
232 - 3x = x + 20
232 - 3x + 3x = x + 3x + 20
232 = 4x + 20
232 - 20 = 4x + 20 - 20
212 = 4x
212/4 = 4x/4
212/4 = x
x = 53
Step-by-step explanation:
(a) x=2, x=6/7
x²-(sum of a number)x+(product of number)=0
x²-(2+(6/7))x+(2×(6/7))=0
x²-(20/7)x+(12/7)=0
7x²-20x+12=0
(b)= x=-1/2, x=-2/3
x²-(sum of number)x+(product of number)=0
x²-((-1/2)-(2/3))x+((-1/2)×(-2/3))=0
x²-(-7/6)x+(2/6)=0
6x²+7x+2=0
