The equation is, x/3 -4 = x/5 ?
Thank you very much :D
This is how it works...
x/3 - 4 = x/5
find a common denominator, 15
5x/15 - 4 = 3x/15
Subtract 3x/15 from both sides
2x/15 - 4 = 0
Add 4 to both sides
2x/15 = 4
Divide each side by 2
x/15 = 2
Multiply each side by 15
x = 30
I would say multiple the 4 on both top and bottom by 3... --> x/3 -12/3 = x/5 then and the left side together... -->x-12/3 = x/5 then cross muliply... ---> 5x-60 = 3x subtract 5x... --> -60 = -2x then divide by -2 --> x=30
im sorry I check my work and the answer is 30 but where did you hear it was to because if you check your work 2 doesn't work but 30 does
yeah I know but my teacher gave me an exam review with the answers but I don't understand how 2 works out either.. but it is the answer..
thanks for trying but it's actually x= 2
but I dont know how to get it..
the answer is 5
