Question

Solve for b.
3(b−4)+5b=44
b =

Answer 1

7

Explanation:

3(b-4)+5b=44 3b-12+5b=44 3b+5b=56 8b=56 56/8=7

Answer 2

7

Explanation:

Given equation is
`\[3(b-4)+5b=44\]`.

Simplifying the equation,

`\[3b-12+5b=44\]`

`\[=> (3+5)b-12=44\]`

`\[=> 8b=44+12\]`

`\[=> 8b=56\]`

`\[=> b=(56)/(8)\]`

`\[=> b=7\]`

Hence the required value of b is 7

Validation:

`\[3(b-4)+5b\]`

`\[=3(7-4)+5*7\]`

`\[=3*3+5*7\]`

`\[=9+35\]`

`\[=44\]`
