Question

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

Answer 1

Answer:

7x−14

Step-by-step explanation:

Factor 3(x+2)+4(x−5)

7x−14

=7(x−2)

Answer:

7(x−2)

Answer 2

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:

$x = \frac {24} {7}$
