For this case we must find the value of "x" of the following expression:


3 (x + 2) +4 (x-5) = 10

We apply distributive property to eliminate parentheses:


3x + 6 + 4x-20 = 10

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.


7x-14 = 10

We add 14 to both sides:


7x = 10 + 14\\7x = 24

We divide between 7 on both sides:


x = \frac {24} {7}

Answer:


x = \frac {24} {7}
