Question

Considerando x a incógnita:
a) a+bx=5a-3x =

B) 4ax-2b=ax+2b=

C) ax-1=4+bx =

Me ajudem pfv!!!

Answer 1

A) a +b x = 5 a - 3 x=  3 x + b x = 5 a - a =  x( 3 + b) = 4 a  --------------------------->  x = 4 a/3 + b

B) 4 a x - 2 b = a x + 2 b = 4 a x - a x = 2 b + 2 b = 3 a x = 4 b --------------------------->x = 4 b/3 a

C) a x - 1 = 4 + b x = a x - b x = 4 + 1 = x(a - b) = 5 ------> x =  5/a - b
