Question

Hallar el valor de x en las siguientes ecuaciones. a) x + 5 = 14 b) x – 3 = -8 c) 2.x + 9 = +1 d) 3+x−2 = 3+1 e) 5+x = 1- x

Answer 1

a). X + 5 = 14
X = 14 - 5
X = 9

b). X - 3 = -8
X = -8 - 3
X = -5
c). 2.x + 9 = 1
2x = 1 - 9
2x = -8
X = -8/2
X = -4
d). 3 + X - 2 = 3 + 1
X = 4 - 1
X = 3
e). 5 + X = 1 - X
2X = 1 - 5
X = -4/2
X = -2
