Question

6r-r+8(15-r)+23-6

Answer 1

Answer:

Therefore,

$6r-r++(15-r)+23-6 = -3r+137$ i.e

$6r-r+8(15-r)+23-6$    and

$-3r+137$ are Equivalent .

Step-by-step explanation:

To Check:

$6r-r+8(15-r)+23-6$ and

$-3r+137$ is Equivalent or Not

Solution:

Consider,

$6r-r+8(15-r)+23-6$  

Step 1 . Apply Distributive Property , A(B+C)=AB+AC we get

$6r-r+8\times 15-8\times r+23-6$  

$6r-r+120-8r+23-6$  

Step 2 . Combining Like Terms i.e r terms and the numbers we get

$6r-r-8r+120+23-6$  

$-3r+137$  

Which is Equivalent to the given expression

$-3r+137$

Therefore,

$6r-r+8(15-r)+23-6= -3r+137$   i.e

$6r-r+8(15-r)+23-6$      and

$-3r+137$                  ..........are Equivalent .
