Answer:

The value of variable r in the equation
10r+4=8 is
$\mathbf{r=0.4}$

Explanation:

We need to find the value of variable r in the equation
10r+4=8

Step 1: Write the equation

10r+4=8

Step 2: Subtract 4 on both sides

$10r+4-4=8-4\\10r=4$

Step 3: Divide both sides by 4

$(10r)/(10)=(4)/(10)\\r=0.4$

So, The value of variable r in the equation
10r+4=8 is
$\mathbf{r=0.4}$
