let's firstly convert the mixed fractions to improper fractions, and then use the LCD, which in this case is 4, to sum them up.

$\bf \stackrel{mixed}{3\frac{1}{4}}\implies \cfrac{3\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{13}{4}}~\hfill \stackrel{mixed}{4\frac{3}{4}}\implies \cfrac{4\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{19}{4}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{13}{4}+\cfrac{19}{4}\implies \stackrel{\textit{using the LCD of 4}}{\cfrac{13+19}{4}}\implies \cfrac{32}{4}\implies 8$

Answer: 1. x= -12 2. x= 12

Step-by-step explanation:

1. 5(+3)=−45

5x+15−15=−45−15

5x= -60

5x/5 = -60/5

x = -60/5

x= -12

2. 1x/2−4=2

x/2 -4=22−4+4=2+4

/2=6

2⋅2=2⋅6

x=2⋅6

x= 12
