Angle sum of a triangle = 180°
Therefore:
Equation No. 1 -
2 ( 2x - 4 ) + 5y = 180°
2 ( 2x - 4 ) + 5 [ ( 2x - 4 ) / 5 ] = 180
4x - 8 + [ 5 ( 2x - 4 ) / 5 ] = 180
4x - 8 + 2x - 4 = 180
4x + 2x = 180 + 8 + 4
6x = 192
x = 192 / 6
x = 32°
Equation No. 2 -
5y = 2x - 4
y = ( 2x - 4 ) / 5
ANSWER:
x = 32°

Step-by-step explanation:
Solution for the given fractions
7/9 + 2/3 = ?
The common denominator of the two fractions is: 9
7/9 = (1*7)/(1*9) = 7/9
2/3 = (2*3)/(3*3) = 6/9
Fractions adjusted to a common denominator
7/9 + 2/3 = 7/9 + 6/9
(6+7)/9 = 13/9
