[tex] \frac{3}{4} [/tex] +x = [tex] \frac{7}{4} [/tex]
x= [tex] \frac{7}{4} [/tex] - [tex] \frac{3}{4} [/tex]
x= 4/4 = 1
x+ [tex] \frac{3}{10} [/tex] = [tex] \frac{10}{10} [/tex]
x= [tex] \frac{10}{10} - \frac{3}{10} = \frac{7}{10} [/tex]
5/5 + x = 7/5
x=7/5-5/5
x= 2/5
6/8+x= 10/8
x=10/8-6/8
x=4/8
x=1/2
