Answer:
Step-by-step explanation:
18x + -2x = 16x in other words 18x - 2x = 16x
54/x = 6...multiply both sides by x
54 = 6x...divide both sides by 6
54/6 = x
9 = x

Answer:
Second option: y = 8x-3
Step-by-step explanation:
The equation tha satisfies the given values will be the required linear equation
So,
y = 8x + 45
For x=3 and y=21
21 = 8(3) +45
21 = 24+45
21≠69
As this equation is not satisfied by the values, it is not the correct option..
For y = 8x-3
x=3,y=21
21 = 8(3)-3
21 = 24-3
21=21
x=5, y=37
37 = 8(5)-3
37=40-3
37=37
x=7, y=53
53 = 8(7)-3
53 = 56-3
53 = 53
As the equation is true for all values of x and y. This is this correct option..
