Step-by-step explanation:12 is half of 24
Answer should be be half of 1.5
It doesn’t really matter which variable you isolate first but usually you would use the one that’s by itself already. like for example one of the equations was y = 8. you would already have your y solve for so you would just have to plug that in for y in the other equation. personally, i usually do x first unless one of the equations has either x or y by itself already. i think its easier to just do x first and then solve for y after that, but it just depends on what the equations are; sometimes it might be easier to just do y first. hope this helps!
To solve this problem you must apply the proccedure shown below:
You must switch the variables, and then, you must solve for
, as following:

Therefore, as you can see, the answer is:
