Question

How many solutions exist for the given equation?

0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)

Answer 1

you have to distribute brackets by left side number

Answer 2

distrbute? you have a+a on one side .. thats just 2a

Answer 3

0.35(x + 20) + 0.35(x + 20) = 2(.35)(x+20)

Answer 4

if you cant see the solution before hand, then yeah, you would do better to find the solutions by solving it

Answer 5

as i see it, youve got parallel lines ....
