Question

solve the equation 3x+2(x+2)=20-(2x-5)

Answer 1

3x+2x+4=20-2x+5

5x+4=25-2x

5x+2x=25-4

7x=21

x=21/7

x=3


I hope this will help you

Answer 2

Given,

$3x + 2(x + 2) = 20 - (2x - 5)$
Multiplying the numbers in the brackets,
we have,

$3x + 2x + 4 = 20 - 2x + 5$

$5x + 4 = 25 - 2x$
Transposing 2x to LHS and 4 to RHS,
we have,

$5x + 2x = 25 - 4$

$7x = 21$

$x = \frac{21}{7}$
$x = 3$


So,
the value of x is 3
