Answer:

12x + 3

Step-by-step explanation:

10x + x + x is 12x

-7 + 10 is 3

You just have to separate the variables and constants from each other, simplify those, and then put them together to form an expression.

triangles
Reorder like terms to simplify

10x+x+x-7+10

Group like terms/variables & solve
(10x+x+x)-7+10
(12x)-7+10
12x+3

The answer is 12x+3

+ Remember that -7+10 is the same as doing 10-7
