------> by complementary angles

and

Distribute and simply 7-2(x-5)+3x
KonstantinChe [14]

The given expression is

7-2(x-5)+3x

First, we use the distributive property to get rid of the parenthesis.

7-2x+10+3x

Then, we reduce like terms. -2x and 3x are like terms, also 7 and 10 are like terms.

3x-2x+10+7=x+17<h2>Therefore, the simplest form of the given expression is <em>x + 17</em>.</h2>
