Question

(x-60) + (x/3+50)=180
alguém me ajuda?​

Answer 1

(x - 60) + (x/3 + 50) = 180

x - 60 + x/3 + 50 = 180

x/1 + x/3 - 60 + 50 = 180

3x+x/3 - 10 = 180

4/3 x - 10 = 180

4x - 30 = 540

4x = 540 + 30

4x = 570

x = 570/4

x = 285/2 = 142,5

Answer 2

$(x-60) + (\frac{x}{3} + 50)= 180\\\\\frac{3x-180+x+150= 540}{3} \\\\3x-180+x+150 = 540\\\\4x = 540-150+180\\\\4x = 390+180\\\\4x = 570\\\\x = \frac{570:2}{4:2} \\\\x = \frac{285}{2}$
