Question

alguien me puede explicar las sig ecuaciones 4x=28, 2x+7=47, ax=b, x-11=33, 4x-9=23,
x-a=b, x+15=60, x/2-3=5, x+a=b, 3x+8=38, 2x-15=22, 6x+7=42, 1.7x-2.3=4.5

Answer 1

Es facil veras solo despejas x
x=28/4
x=7

x=(47-7)/2
x=40/2
x=20

x=a/b

x=33+11
x=44

x=(23+9)/4
x=32/4
x=8

x=a+b

x=60-45
x=15

(x-6)/2=5
x-6=5*2
x=10+6
x=16

x=b-a

x=(38-8)/3
x=30/3
x=10

x=(22-15)/2
x=6/2
x=3

x=(42-7)/6
x=36/6
x=6

x=(4.5+2.3)/1,7
x=6,8/1.7
x=4

Listoooo
