Question #1739

What's the first step to 5x+5=2/10x+29 ?

Expert's answer

The first simplest step is to combine similar terms

5x+5=2/10x+29 |-5

5x = 2/10x + 24 | *10x

50x^{2} = 2 + 240x

50x^{2} -240x -2 =0 | 2

25x^{2} -120x - 1 = 0

D = 60^{2} + 25 = 3625

x_{1} = (60 + 5√145)/25 = (12 + √145)/5

x_{2} = (60 - 5√145)/25 = (12 - √145)/5

5x+5=2/10x+29 |-5

5x = 2/10x + 24 | *10x
