Answer:
X = 8 And y = 1/5
Step-by-step explanation:
add equaction i and education ii,
2 -5y = 1
2x +5y = 17
------------------
2+2x = 18
or, 2x = 18 - 2
or X = 16/2
or X = 8
Again from equation i,
2 - 5y = 1
or, -5y = 1 - 2
or, -5y = -1
or, y = -1/-5 (cut the subtraction sign)
or, y = 1/5
Answer:
a= 11
Step-by-step explanation:
9a+ 6°+75° =180° (straight angle, they are called supplementary angles. so sum is equal to 180°
9a +81 = 180
9a= 99
a= 11
