  \:  \:  \:  \:  \:  \:  \: \frac{3x}{4}  +   \frac{2}{7} =  \frac{5}{4}   \\   \\ \frac{7(3x) + 4(2)}{28}  =  \frac{5}{4}  \\  \:  \:  \:  \:   \frac{21x + 8}{28}  =   \frac{5}{4}  \\  \:  \:  \:  \:  \:  \:  \: 4(21x + 8) = 28(5) \\ \:  \:  \:  \:  \:  \:  \:  84x + 32 = 140 \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  84x = 140 - 32 \\ \:  \:  \:  \:  \:  \: \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  84x = 108 \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   x =  \frac{108}{84}  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:   \: \:  \:  \:  \:  \:  \:  \:  \:  \:  x =  \frac{9}{7}
