Answer 1

Hallar El Valor De "x" De Las Siguientes Ecuaciones

➊ 3x - 8 = 10

3x - 8 = 10
3x = 10 + 8
3x = 18
x = 18/3
x = 6

➋ x/2 - 3 = 5

x/2 - 3 = 5
x/2 = 3 + 5
x/2 = 8
x = 8 x 2
x = 16

➌ 1.7x - 2.3 = 4.5

1.7x - 2.3 = 4.5
1.7x = 2.3 + 4.5
1.7x = 6.8
x = 6.8/1.7
x = 4

➍ 2x - 15 = 28

2x - 15 = 28
2x = 15 + 28
2x = 43
x = 43/2
x = 21.5
