Answer: & Step-by-step explanation:

1)\frac{x+1}{2x+3}=\frac{3}{8}\\\\  =>8x+8=6x+9\\\\=>8x-6x=9-8\\\\=>2x=1\\\\=>x=\frac{1}{2}

2)\frac{5x+4}{7x+4}=\frac{3}{4}\\\\  =>20x+16=21x+12\\\\=>21x-20x=16-12\\\\=>x=4

3) \frac{x-5}{3}=\frac{x-3}{5}\\\\  =>5x-25=3x-9\\\\=>5x-3x=25-9\\\\=>2x=16\\\\=>x=8

4)\frac{t-3}{5}=\frac{2t+1}{3}\\\\  =>3t-9=10t+5\\\\=>10t-3t=-9-5\\\\=>7t=-14\\\\=>t=-2

In all these cases we only use cross multiplication.

Hope helps you....
