Question

(2x + 3y) + (4x - 3y) = 11+(-5)

Which of the following is equivalent to the equation above?
A. 6x=10
B. 6x=16
C. 6x+6y=6
D. 6x+6y=16

Answer 1

The correct option should have been
`6x=6`.

Explanation:

Given the expression

`\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)`

solving the expression

`\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)`

Remove parentheses: (a) = a

`2x+3y+4x-3y=11-5`

Group like terms

`3y-3y+2x+4x=11-5`

Add similar elements

`6x=6`

It is clear that not a single given option is
`6x=6`. It means no option is correct. It seems you mistyped the correct options.

The correct option should have been
`6x=6`.
