Question

respuesta del valor de las siguientes ecuaciones. 2x=8, 2+x=8 ×+×+×+×=8 2+3x=8 3x-5=16 31×-57=15

Answer 1

2x=8
x = 8/2
x =4


2+x=8
x = 8-2
x = 6

×+×+×+×=8
4x= 8
x = 8/4
x = 2


2+3x=8
3x = 8-2
3x = 6
x = 6/3
x = 2


3x-5=16
3x = 16+5
3x = 21
x = 21/3
x = 7


31x-57=15
31x = 15+57
31x = 72
x = 72/31
