1/2r−3=3(4−3/2r) plzzzzzzz help!

1 answer:

4 0

Answer:
r= 3

Explanation:
1. Write the division as a fraction
1/2r-3=3(4-3/2r)

2.Distribute the 3 through the paranthesis
1/2r-3=12-9/2r

3.Multiply both sides by 2
r-6=24-9r

4. Swap -6 and -9 together by changing their signs
r+9r= 24+6

5.Add them together
10r=30

6. Divide both sides by 10
r=10

Hope this helped :)

How many solution does this following equation have? -7x-10-15x=-22x+83 A. No solution B. Exact 1 solution C. Infinite solution

Answer:

A. No Solution

Step-by-step explanation:

To solve for x we would just simplify the equation so it is easier to work with. First we will combine the -7x and the -15x and when you combine then you will get -22x so the equation will look like this $-22x-10=-22x+83$ now we would add 22x to both sides and our equation will be $-10=83$ and that is not correct so the answer would be A. No solution
