How do you subtract integers?<br> like -81-(-34)
DedPeter [7]

Answer:

-47

Step-by-step explanation:

For this problem, we can use the rule "two negatives make a positive".

-81-(-34)

= -81 + 34

If you subtract 34 from 81, you find the opposite positive/negative answer.

81 - 34 = 47

Change all of the positive/negative signs:

-81 + 34 = -47

PLEASE HELP FAST!!!!!!!!!!!
san4es73 [151]

Answer:

First expression         8y +4x +10

Second expression    7x-3y +6

If you want to combine both expressions: 5y +11x +16

Step-by-step explanation:

Like terms are the terms which have same variables and powers/roots.

Example: 7x and 2x are like terms because the variables are both "x". So we can combine in 9x

In an expression, only like terms can be combined. We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily. To combine like terms, we add the coefficients and keep the variables the same

10y + 3x + 10 + x -2y  

10y-2y=8y          3x+x=4x

so         8y +4x +10

3x - y + 4x + 6 - 2y

3x+4x=7x              -2y -y = -3y

so  7x-3y +6
