Question

Simplify the following expression.


(10x - 12y) + (49x + 67y)

Answer 1

Just simply add the number of x's and y's together.

What do you have when you do that?

Answer 2

59x + 79y





-2x + 55y





-2x + 79y





59x + 55y

Answer 3

\[(10x-12y)+(49x+67y)= (10x+49x)+(67y-12y)= x(10+49)+ y(67-12)= 59x+55y\]

Answer 4

Add the number of x's (10 + 49) to simplify the number of x's in the equation.
Do the same for the number of y's (12 + 67).
How many x's and y's do you have?

Answer 5

yup

Answer 6

I don't get it I try using a helpful calculator but its wrong?

Answer 7

Or maybe, if that doesn't make sense, I'll use colors.
\(\bf\color{black}{(}\color{cyan}{10x}\color{black}{-}\color{magenta}{12y}\color{black}{)}\) + \(\bf\color{black}{(}\color{cyan}{49x}\color{black}{+}\color{magenta}{67y}\color{black}{)}\)

Add the blue ones together:
\(\bf\color{cyan}{10x}\color{black}{+}\color{cyan}{49x}\)
to get \(\bf\color{cyan}{59x}\)

Then add the y's:
\(\bf\color{magenta}{12y}\color{black}{+}\color{magenta}{67y}\)
to get \(\bf\color{magenta}{79y}\).

So, you have
\(\bf\color{cyan}{59x}\) and \(\bf\color{magenta}{79y}\)

Does that make sense?

Answer 15

No it shouldn't, that's not even one of the choices. ;p

Answer 16

The answer should be 59x+55y because in the first parenthesis it has -12y

Answer 17

It just wanted the expression to be simplified, not the answer. :p

Answer 18

Yes, I know but you added the y's incorrectly lol

Answer 19

\(\bf\color{black}{(}\color{cyan}{10x}\color{red}{-}\color{magenta}{12y}\color{black}{)+}\bf\color{black}{(}\color{cyan}{49x}\color{red}{+}\color{magenta}{67y}\color{black}{)}\)
One of the y values is + and one is -
