Question

What is the value of r in the equation 2(2r + 8) = 3r + 16?

Answer 1

2(2r + 8) = 3r + 16
4r + 16 = 3r +16
4r - 3r = 16 - 16
r = 0

Answer 2

The value of r is 0

Explanation:

Given the equation 2(2r + 8) = 3r + 16

We have to find the value of r

2(2r + 8) = 3r + 16

By distributive property,

a(b+c)=ab+ac

⇒ 2(2r)+2(8)=3r+16

⇒ 4r+16=3r+16

⇒ 4r-3r=16-16

⇒ r=0

hence, the value of r is 0.
