Question

respostas das equações 10x+26-x=4x e x/2-18=3x-168 ,,x/2+3x/4+1=5/3+x+1/3

Answer 1

 10x+26-x=4x
9x - 4x = -26
5x = -26
x = -26/5

 x/2-18=3x-168
3x - x/2 = - 18 - 168
6x-x/2 = -372/2
5x= - 372
x = -372/5

x/2+3x/4+1=5/3+x+1/3
6x+9x+12=20 +12x + 4
15x - 12x = 24 - 12
3x = 12
x = 12/3
x = 4
