Simplify the expression. include the steps! (2x+6)+(1x+7)

(2x + 6) + (1x + 7)

To solve this expression, you must combine like terms.

Like terms are terms with the same variable(s) and same variables to the same powers.

The like terms in this expression are (2x + 1x) and (6 + 7).

Combine them (add them). Your new expression should look like this:

3x + 13

This expression cannot be simplified any farther, so your answer to this problem is 3x + 13.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: the answer is b. i think hope i got it correct
