Question

cual es el resultado de esta ecuaciones a) 7x+4=10-3x
b)2x+3=-x

Answer 1

a)
7x + 4 = 10 - 3x
7x + 3x = 10 - 4
10x = 6
x = 6/10
x = 3/5

b)
2x + 3 = -x
3x = -3
x = -3/3
x = -1

Answer 2

7x + 4 = 10 - 3x

7x + 3x = 10 - 4

10x = 6

x = 6/10

x = 3/5

Solución : 

x = 3/5
---------------------------------------

2x + 3 = - x

2x + x = - 3

3x = - 3

x = -3/3

x = - 1

Solución : 

x = - 1
