PLEASE HELP WITH THIS RSM QUESTION

x=(b+ac)/(2c-ab)

Step-by-step explanation:

Cross multiply:

2xc-ac=abx+b

Move the values with x to one side:

2xc-abx=b+ac

Factor out x:

x(2c-ab)=b+ac

Divide:

x=(b+ac)/(2c-ab)

I have that same problem and this is how I solved:

x=(b+ac)/(2c-ab)

Cross multiply:

2xc-ac=abx+b

Move the values with x to one side:

2xc-abx=b+ac

Factor out x:

x(2c-ab)=b+ac

Divide:

x=(b+ac)/(2c-ab)

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
