Least common multiple=lcm
lcm(9,7)=63
126(8/9 + (x-4)/7 )=
126(7*8+9(x-4)/63=
126(56+9x-36)/63=
126(20+9x)/63= (126/63=2)
2(20+9x)=
40+18x
Answer: 126(8/9 + (x-4)/7 )= 40+18x

Answer:

Step-by-step explanation:
Given the linear function for the traffic fines:

If a fine comes to $292, substitute f(s)=292 and solve for "s" to find the speed of the person:
X+y=-1
x-3y=11
------------- (subtract equation)
4y = -12
y = -12/4
y= -3
-------------- (substitute y)
x-3=-1
x=-1+3
x=2
Answer ----> A (2,-3)
-5x-3y=12
x-3y=-6
you want to multiply the top equation by -1 to swap the signs and make the x's positive like the bottom equation
5x+3y=-12
x-3y=-6
then you have to multiply every value in the bottom equation by 5 so you are able to subtract it from the top equation
5x+3y=-12
5x-15y=-30
---------------- (subtract)
18y=18
y=18/18
y=1
------------------ (substitute y)
x-3=-6
x=-6+3
x=-3
answer = (-3,1)
