Question

Simplify 2x - 8x - 6y + 9 -14 + x + 11y.

5 x - 5 y - 5
-5 x + 5 y - 5
-5 x - 5 y + 5
5 x + 5 y + 5

Answer 1

Correct Question :-

Simplify 2x - 8x - 6y + 9 -14 + x + 11y.

1. 5 x - 5 y - 5
2. -5 x + 5 y - 5
3. -5 x - 5 y + 5
4. 5 x + 5 y + 5

ANSWER :-

${\large{\bf{\ratio{\longmapsto{2x - 8x - 6y + 9 - 14 + x + 11y}}}}}$

● Always note that

• (+) + (+) = +
• (+) + (-) = –
• (-) + (+) = –
• (-) + (-) = +

This is called Sign Conventions of Algebra. This is very helpful while solving this type of question.

Also, Sign will be always of greater number.

SOLUTION :-

${\large{\bf{\ratio{\longmapsto{2x - 8x - 6y + 9 - 14 + x + 11y}}}}}$

${\large{\bf{\ratio{\longmapsto{ - 6x- 6y + 9 - 14 + x + 11y}}}}}$

${\large{\bf{\ratio{\longmapsto{ - 6x- 6y - 5 + x + 11y}}}}}$

${\large{\bf{\ratio{\longmapsto{ - 6x + x - 6y - 5 + 11y}}}}}$

${\large{\bf{\ratio{\longmapsto{ -5x- 6y - 5 + 11y}}}}}$

${\large{\bf{\ratio{\longmapsto{ -5x- 6y + 11y- 5 }}}}}$

${ \underline{ \boxed{ \red{\large{\bf{\ratio{\longmapsto{ -5x + 5y- 5 }}}}}}}}$

So, option 3 is correct.
