In order to solve this, you just need to lose the fraction by multiplying the equation with 6,

1/2 x - 2/3 y = 5 . . . . . . . . .x6

3 x - 4 y = 30

I'm pretty sure you miss write the option C, so i would pick that

The answer is C because Which of the following equations is equivalent to 1/2x-2/3y= c I'd just 6 times as much, so 1/2 times 6 equals 3 and 2/3 times 6 is 4

Mind my hand writing but I’m not sure what sign to put the “-“ or the “+” ?

hello!

so the answer that you put there is actually wrong and i'll tell you why and how to do it

so since you are adding the two:

-8x + 9x = x (so you got this part right)

-12 + 4 = -8 (this is where you got it wrong, -12 added 4 goes up in value to -8)

so the final answer is x - 8

i hope this helped and have a nice day!
