I need help with number 3 please

the answer is C

Well if you follow PEMDAS you would have to do the parentheses first but you can’t subtract 18 from a variable (Z) so then you move on to the 2 and you have to do the opposite so you don’t multiply both sides by 2 you have to divide both sides by 2. And that’s how u get C

22

step-by-step explanation:

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
