Question

How do you solve `(2x - 1) + 50+ ( 3x + 5) = 180`?

Answer 1

`x = 26.2`

Explanation:

`(2x - 1) + 50 + (3x + 5) = 180`

Simplifying the Brackets first..

`2x - 1 + 50 + 3x + 5 = 180`

Collecting like terms..

`2x + 3x - 1 + 50 + 5 = 180`

`5x + 54 = 180`

`5x = 180 - 54`

`5x = 126`

`x = 126/5`

`x = 26.2`

Answer 2

`x=126/5`

Explanation:

Given -

`(2x-1)+50+(3x+5)=180`

Remove the brackets.

[To remove the bracket you must multiply the signs inside the bracket with the sign preceding the bracket. ]

`2x-1+50+3x+5=180`

`5x+54=180`

`5x+54-54=180-54`

`5xcancel(+54)cancel(-54)=126`

`(5x)/5=126/5`

`(cancel5x)/cancel5=126/5`

`x=126/5`
