Question

$\: \\ \frac{1}{2}(x + 3) - \frac{2}{5} (x - 3) \: is \: equal \: to \: x + 3$
​

Answer 1

Step-by-step explanation:

1/2(x+3)-2/5(x-3)=x+3

=x+3/2-2x-6/5=x+3

=x+3(5)-2x-6(2)/10=x+3

=5x+15-4x-12/10=x+3

=5x+15-4x-12=x+3(10)

=x+3=10x+30

=x+3-10x-30=0

-9x-27=0

=-9x=27

=x=27/-9

=x=-3

hence x value is -3
