Solve the equation. 1. 2r - 8 + 5r = 10+r show your work solve the formula for the indicated variable. t= 3u/e, for u

1. r=3      2.  

Step-by-step explanation:

1. Given equation :

To solve this for r , we add 8 and subtracting r on both sides , we get

Now, combine like terms, we get

Dividing 6 on both sides , we get

2. Given equation :

To solve for U , we first multiply E on both sides , we get

Now, divide 3 on both sides , we get

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
