Question

-8/5 - 1/2y= -8/3

Can someone walk me through this? If I recall I need to change each number to a common denominator, just double checking I'm doing this right.

Answer 1

yes

Answer 2

but first you have to take the numbers on the right hand side of the equation and the variables on the left hand side.

Answer 3

so my problem should start out as -8/5 -1/2 +8/3=y and then it should be -48/30 -15/30 +80/30=y correct? @FaiqRaees

Answer 4

no no see -1/2 is being multiplied with y you cant take that on r.h.s
it should be like\[-1/2 *y=-8/3+8/5\]

Answer 5

ahh ok... so after that step my problem should look like -15/30*y=-80/30+48/30 @FaiqRaees

Answer 6

yes

Answer 7

so if i add them together I'm left with -15/30y=32/30... now do i just add the 32 to the 15 and simplify??? @FaiqRaees

Answer 8

sorry id subtract @FaiqRaees

Answer 9

first of all there should be a negative side with 32 correct that first

Answer 10

-15/30y=-32/30

Answer 11

yep
now multiply 30 on both sides

Answer 12

-450/30y=-960/30 @FaiqRaees

Answer 13

so then I'm left with -15y=-32

Answer 14

and final answer would be -32/15 correct?

Answer 15

multiply both sides with -1

Answer 16

15y = 32
y = 32/15

Answer 17

so y=32/15

Answer 18

yes

Answer 19

perfect. thank you! @FaiqRaees

Answer 20

No problem
