Question

Alguém me ajuda por favor ^-^' ♡

Answer 1

a- 5x=98-23
5x= 75
x= 75/5 = 15 

b- 4x= 148-64
   4x= 84
   x= 84/4 = 21
c- 3x+2x= 105-15
5x= 90
x= 90/5 = 18
d- 5x+ 2x-14-6=7
5x+2x= 7+14+6
7x= 27
x= 27/7 = 3

e- -8x+1+18x-60=31
-8x+18x=31-1+60
-10x= 90 (-1)
10x= -90
x= -90/10 = -9

Answer 2

a) 5x = 98-23
x=15
b)4x = 148-64
x = 21
c) 3x+2x = 105-15
5x = 90
x=18
d) 7x = 17-20
x= -2,3
e)-8x+1+18x-60 = 31
-8x+18x = 31+60-1
x = -9
