Question

Answer 1

b) x - 3/2 = 11/4

   x =11/4 + 3/2 = 17/4

Answer 2

a: x+4/5=3/2

=>x=3/2-4/5=15/10-8/10=7/10

b: x-3/2=11/4

=>x=11/4+3/2=17/4

c: 25/3-x=5/6

=>x=50/6-5/6=45/6=15/2

Answer 3

a) \(x=\dfrac{3}{2}-\dfrac{4}{5}\)

\(x=\dfrac{7}{10}\)

b) \(x=\dfrac{11}{4}+\dfrac{3}{2}\)

\(x=\dfrac{17}{4}\)

c) \(x=\dfrac{25}{3}-\dfrac{5}{6}\)

\(x=\dfrac{15}{2}\)

Answer 4

\(a,x=\dfrac{3}{2}-\dfrac{4}{5}=\dfrac{15}{10}-\dfrac{8}{10}=\dfrac{7}{10}\\ b,x=\dfrac{11}{4}+\dfrac{3}{2}=\dfrac{11}{4}+\dfrac{6}{4}=\dfrac{17}{4}\\ c,x=\dfrac{25}{3}-\dfrac{5}{6}=\dfrac{50}{6}-\dfrac{5}{6}=\dfrac{45}{6}\)

Answer 5

\(a)\\ x=\dfrac{3}{2}-\dfrac{4}{5}\\ x=\dfrac{7}{10}\\ b)\\ x=\dfrac{11}{4}+\dfrac{3}{4}\\ \text{x}=\dfrac{7}{2}\\ c)\\ x=\dfrac{25}{3}-\dfrac{5}{6}\\ x=\dfrac{45}{6}\)

Answer 6

\(a,x+\dfrac{4}{5}=\dfrac{3}{2}\\ x=\dfrac{3}{2}-\dfrac{4}{5}\\ x=\dfrac{15}{10}-\dfrac{8}{10}\\ x=\dfrac{7}{10}\\ b,x-\dfrac{3}{2}=\dfrac{11}{4}\\ x=\dfrac{11}{4}+\dfrac{3}{2}\\ x=\dfrac{11}{4}+\dfrac{6}{4}\\ x=\dfrac{17}{4}\\ c,\dfrac{25}{3}-x=\dfrac{5}{6}\\ x=\dfrac{25}{3}-\dfrac{5}{6}\\ x=\dfrac{50}{6}-\dfrac{5}{6}\\ x=\dfrac{45}{6}\\ x=\dfrac{15}{2}\)

Answer 7

a) x + 4/5 = 3/2

           x    = 3/2 - 4/5

           x    = 7/10

b) x - 3/2 =11/4

           x   = 11/4 + 3/2

           x   = 17/4

c) 25/3 - x =5/6

               x = 25/3 - 5/6

                x = 45/6

Answer 8

a) \(x+\dfrac{4}{5}=\dfrac{3}{2}\)

   x          = \(\dfrac{3}{2}-\dfrac{4}{5}\)

   x          = \(\dfrac{15}{10}-\dfrac{8}{10}\)

  x           = \(\dfrac{7}{10}\)

b) \(x-\dfrac{3}{2}=\dfrac{11}{4}\)

    x          = \(\dfrac{11}{4}+\dfrac{3}{2}\)

    x          = \(\dfrac{11}{4}+\dfrac{6}{4}\)

    x          = \(\dfrac{17}{4}\)

c ) \(\dfrac{25}{3}-x=\dfrac{5}{6}\)

               x  = \(\dfrac{25}{3}-\dfrac{5}{6}\)

               x  = \(\dfrac{50}{6}-\dfrac{5}{6}\)

               x = \(\dfrac{45}{6}\)

              x  = \(\dfrac{15}{2}\)

Answer 9

a) x+\(\dfrac{4}{5}\)=\(\dfrac{3}{2}\)
            = \(\dfrac{3}{2}\)-\(\dfrac{4}{5}\)
            =\(\dfrac{7}{10}\)
b)x-\(\dfrac{3}{2}\)=\(\dfrac{11}{4}\)
          =\(\dfrac{11}{4}\)+\(\dfrac{3}{2}\)
          =\(\dfrac{17}{4}\)
c)\(\dfrac{25}{3}\)-x=\(\dfrac{5}{6}\)
           =\(\dfrac{25}{3}\)-\(\dfrac{5}{6}\)
            =\(\dfrac{15}{2}\)

Answer 10

a) x+ \(\dfrac{4}{5}=\dfrac{3}{2}\)

\(x=\dfrac{3}{2}-\dfrac{4}{5}\)

x = \(\dfrac{15}{10}-\dfrac{8}{10}=\dfrac{7}{10}\)

b) x - \(\dfrac{3}{2}=\dfrac{11}{4}\)

x =\(\dfrac{11}{4}+\dfrac{3}{2}\)

x= \(\dfrac{22}{8}+\dfrac{12}{8}=\dfrac{10}{8}\)

x= \(\dfrac{5}{4}\)

c) \(\dfrac{25}{3}-x=\dfrac{5}{6}\)

x= \(\dfrac{25}{3}-\dfrac{5}{6}\)

x= \(\dfrac{150}{18}-\dfrac{15}{18}\)

x= \(\dfrac{113}{18}\)
