Question

5x+4 = 3x+8
7x-6 = 4x+3
6x+4 = 8x-2
4x+9 = 7x-3

Answer 1

Resolver.
5x + 4 = 3x +8
5x - 3x = 8 -4
2x = 4
x = 4/2
x = 2
---------------------------------------------------------------------------------------------
7x - 6 = 4x + 3
7x - 4x = 3 +6
3x = 9
x = 9/3
x = 3
----------------------------------------------------------------------------------------------
6x + 4 = 8x - 2
4 + 2 = 8x - 6x
6 = 2x
6/2 = x
3 = x
x = 3
-----------------------------------------------------------------------------------------------
4x +9 = 7x - 3
9 +3 = 7x - 4x
12 = 3x
12/3 = x
4  = x
x = 4
