Question

-4r-8(r-6)=7(5r-1)+8

Answer 1

r = 1

Explanation:

In this question, we have to solve for the vallue of "r". We will use the distributive property shown below to ease our process.

Distributive Property:

a(b+c) = ab + ac

Now, lets solve this:

`-4r-8(r-6)=7(5r-1)+8\\-4r-8r+48=35r-7+8\\-12r+48=35r+1\\48-1=35r+12r\\47=47r\\r=(47)/(47)\\r=1`

As we have seen the value of r is "1"
