Hello , could you explain me how the followin equation works ?
We search for x
Thanks for your time !
We can write
1x =(0.2*x)+0.6 subtract 0.2 x from both sides
.8x = .6 divide both sides by .8
x = .6 / .8 = 6 / 8 = 3 / 4 = .75
Here is another method to solve this equation. I like this method as it gets rid of all the pesky fractions and/or decimals in an equation:
|\(x=0.2x+0.6\)||Multiply both sides of the equation by 10.|
|\(10x=2x+6\)||By multiplying by 10, we have eliminated any decimals in the equation. Subtract 2x from both sides.|
|\(8x=6\)||Divide by 8 on both sides.|
For this particular problem, the method one chooses here is trivial, as the problem is too short to make a noticeable difference. However, I find that I prefer (and have ultimately defaulted to) this method of eliminating any and all decimals and/or fractions to ease the solving process for more complicated equations.
