Question

determine o valor de cada equaçao:a)4x-2=18 b)2y-3+y=15 c)1/2x+2=32

Answer 1

a)4x-2=18 ==. 4x = 18+2 ==. 4x = 20 ==. x = 5
=================================================
b)2y-3+y=15 ==> 3y =15+3==> 3y=18==> y=6
============================================
c)1x+2=32 ==> x+4=64 ==. x = 64-4 ==> x = 60
   2

Answer 2

A) 4x = 18+2 = 20/4 = 5 B) 3y = 15+3 18/3 = 6y C) 0.5x = 32-2 = 30 /0.5 = 60
