Answer:
don't know which question?
Step-by-step explanation:
¿???????
12 - x = 20 - 5x
You see that -x and -5x both have an 'x' variable? This means they are 'like' terms. To get -x to the other side, we must add (if like terms are on opposite sides, do the opposite of what the sign says, e.g. - will be +)
12 = 20 - 4x
Now move 20 to the other side. Remember, do the opposite! Since 20 is positive, we must minus 20 to the other side.
-8 = -4x
To get x by itself, you will need to get rid of the coefficient of -4. -4x basically means -4 times x, so the opposite of that would be divide! Divide by -4
2 = x (Since both sides have a negative, they cancel out to give a positive)
x = 2
Answer: $4.25
Process:
22.75-1.50=21.25
21.25 divided by 5= $4.25 per yard
Mark me as brainliest pls
Good luck
Answer:
y=10/3 i think if that's what youre asking
Step-by-step explanation:
First, you would subtract 4.25 from 6.25 and that would be equal to 2.
Then, you would take 2.25z and subtract it from 3.5z and it would equal 1.25z.
Next, you would separate the z by dividing 1.25 on both sides. Z=1.6
