-3r-8(8r+8)=-9(-4+9r)

natulia [17]

Answer:

r= 7.14 (rounded to 2 decimal places)

Step-by-step explanation:

We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.

Distributive property is a(b+c) = ab + ac

Now, the steps of solving are shown below:

$-3r-8(8r+8)=-9(-4+9r)\\-3r -64r-64=36-81r\\-67r-64=36-81r\\-67r+81r=36+64\\14r=100\\r=\frac{100}{14}\\r=7.14$

Hence, value of r is 7.14 (rounded to 2 decimal places)
