Answer:

a) 2.5

b)2.33

Step-by-step explanation:

a)

[tex]4x-\frac{1}{2}= x+7[/tex]

Bring the numerals to the right hand side and the x terms to the left hand side

[tex]4x-x=7+\frac{1}{2}[/tex]

Simplify

[tex]3x=\frac{15}{2}[/tex]

Divide 3 on both sides, to get x

[tex]x=\frac{5}{2} =2.5[/tex]

b)

[tex]3x+2=2x+\frac{13}{3}[/tex]

Bring the numerals to the right hand side and the x terms to the left hand side

[tex]3x-2x=\frac{13}{3}-2[/tex]

Simplify

[tex]x=\frac{7}{3} =2.33[/tex]
