What is 1/2 (3/5x - 8) + 7/4 (2/5x + 4) ?

(Simplify the expression by distributing and combining like terms)

1/2 ((3:5x) - 8) = ((3-40x) : 5x) 1/2

3-49x/10x

+

7/4 (2+20x/5x) = (14+140x) / 20x

=14 (1+10x) / 20x

=7+70x/10x

= (3+49x/10x + 7+70x) / 10x

= (3+7+70x-40x) / 10x

= (10+30x) / 10x

=10 (1+3x) / 10x

= (1+3x) / x

(1/2) * ((3/5) * x-8) + (7/4) * ((2/5) * x+4) = 0

1/2 * (3/5*x-8) + 7/4 * (2/5*x+4) = 0

1/2 * (3/5*x-8) + 7/4 * (2/5*x+4) = 0

x+3 = 0

x+3 = 0

x+3 = 0 / / - 3

x = - 3

x = - 3
