4(x+2)/5=7+5x/13
4x+8/5=7+5x/13
13 (4x+8) = 5 (7+5x)
52x+ 104 = 35+25x
52x-25x = 35-104
27x = 69
X = 69/27
X = 2.55
4x+8/5=7+5x/13
13 (4x+8) = 5 (7+5x)
52x+ 104 = 35+25x
52x-25x = 35-104
27x = 69
X = 69/27
X = 2.55

(4x+8)/5=7+5x/13
4x/5+8/5=7+5x/13
4x/5-5x/13+8/5=7
52x/65-25x/65=7-8/5 ( taking lcm on left side )
27x/65=35/5-8/5 ( taking lcm on right side )
27x/65=27/5
x=27/5*65/27 ( * for multiplication )
x=65/5
x=13
