Question

how to clear then substitution
x/2- y/3=5/6
x/5-y/4=29/10

Answer 1

multiply the first by 6
the second by 20

Answer 2

in questions like this, it is usually best to first get rid of the fractions

Answer 3

you can do that in the first equation by multiplying it by \(2*3=6\) - that will remove both the denominators 2 and 3

Answer 4

similarly, multiply the second equation by \(5*4=20\) - which will get rid of both the denominators 5 and 4

Answer 5

write down what you get after these steps

Answer 6

6x-6y=30
5x-4y=20

Answer 7

that does not look correct

Answer 8

let me do the first one for you - and then you can reattempt the second one

Answer 9

ok
