ECUACIONES DE PRIMER GRADO
a) x + 7 = 14 = x=7
b) 5 + x = 18 = x=13
c) 19 = x + 3 = x =16
d) 52 = x - 10 = x =62
e) 2x + 4 = 6 = x =1
f) y - 8 = 10 = y =9
g) 5 ( x + 1 ) = 25 = x=4
h) 25 - 15 = 4x - 10 = x=5
Explicación paso a paso:
a) x + 7 = 14
x = 14 -7
x =7
b) 5 + x =18
x +5 =18
x =18 - 5
x =13
c) 19 = x + 3
19 - x = 3
- x =3 -19
- x = - 16
x = - (-16)
x = 16
d) 52 = x - 10
52 - x = - 10
- x= - 10 - 52
- x = - 62
x = -(-62)
x =62
e) 2x +4=6
2x= 6-4
2x =2
x =1
f) y - 8 =10
y = 1 +8
y =9
g) 5 ( x - 1) = 25
5x - 5 =25
5x = 25 +5
5x =30
x =6
h) 25 - 15 = 4x - 10
10 = 4x - 10
10 - 4x = -10
- 4x = -10 -10
- 4x = -20
4x =20
x =5
Problema 1:
X + 7 = 14
X = 14 - 7
X = 7
Problema 2:
5 + X = 18
X = 18 - 5
X = 13
Problema 3:
19 = X + 3
19 - 3 = X
16 = X
Problema 4:
52 = X - 10
52 + 10 = X
62 = X
Problema 5:
2x + 4 = 16
2x = 16 - 4
X = 12
Problema 6:
Y - 8 = 10
Y = 10 + 8
Y = 18
Problema 7:
25 - 15 = 4x - 10
25 - 15 + 10 = 4x
20 = 4x
X = 5
