Answer:
x = 19.6
Step-by-step explanation:
If we need to find the value of x then first we need to
(7x-25) + (3x +9) = 180 (angles at the same side of transversal will be equal to 180 degree )
10x -16 = 180
10x = 180 +16
10x = 196
x = 196/10
x = 19.6
Answer:
(6 , -1)
Step-by-step explanation:
2x+ y = 11 ----------------(I)
y = 11 - 2x --------------------(II)

Multiply the whole equation by 2

x - 10y = 16 --------------------(III)
Substitute y = 11- 2x in equation (III)
x - 10(11 - 2x) = 16
x - 110 + 20x = 16
21x - 110 = 16
21x = 16 +110
21x = 126
x = 126/21
x = 6
Plugin x = 6 in equation (II)
y = 11 - 2*6
y = 11 - 12
y = -1
4(x+1) is the only one equal to 0
