Hola me ayudan? A) 7x + 3 = 2x + 8 b)7x + 12 = 4x - 17.
En resumen
7x - 2x = 8 - 3 5x = 5 x = 5 / 5 x = 1 b)7x - 4x = 17 - 12 3x = 15 x = 15 / 3 x = 5.
7x - 2x = 8 - 3
5x = 5
x = 5 / 5
x = 1
b)7x - 4x = 17 - 12
3x = 15
x = 15 / 3
x = 5.
A)
7x + 3 = 2x + 8
7x—2x = 8—3
5x = 5
x = 5 / 5
X = 1
B)
7x + 12 = 4x—17
7x—4x = —17—12
3x = —29
X = —29 / 3.
