Question

2X+5=7 b)5/3=10X-7/6(X+1)

Answer 1

Saludos,

2x +5 = 7
2x = 7-5
x = 2/2
x = 1

5/3 = 10x - 7/6(x+1)
5/3 = 10x - (7(x+1))/6
5/3 - 7/6 = (60x - 7(x+1))/6
5/3 = (60x - 7 - 7x)/6
5/3 = ((60x - 7x) - 7)/6
5/3 = (53x -7)/6
5/3 * 6 = 53x -7
30/3 = 53x - 7
10 + 7 = 53x
17/53 = x
x = 17/53 ≈ 0,32
