[tex]\sf\frac{2}{3}x = \frac{6}{4}[/tex]
[tex] \sf \: x = \frac{6}{4} \div \frac{2}{3} [/tex]
[tex] \sf \: x = \frac{6}{4} \times \frac{3}{2} [/tex]
[tex] \sf \: x = \frac{6 \times 3}{4 \times 2} [/tex]
[tex] \sf \: x = \frac{18}{8} [/tex]
[tex] \sf \: x = \frac{9}{4} [/tex]
----
2x - 1
[tex] \sf = 2( \frac{9}{4} ) - 1[/tex]
[tex] \sf = \frac{2 \times 9}{4} - 1[/tex]
[tex] \sf = \frac{18}{4} - 1[/tex]
[tex] \sf = \frac{9}{2} - 1[/tex]
[tex] \sf = \frac{9 - 1}{2} [/tex]
[tex] \sf = \frac{7}{2} [/tex]
[tex] \sf = 3 \frac{1}{2} [/tex]
[tex]\sf\frac{2}{3}x = \frac{6}{4}[/tex]
[tex]\sf\frac{2}{3}x = \frac{3}{2}[/tex]
[tex]\sf \: x = \frac{3}{2} \times \frac{3}{2} [/tex]
[tex]\sf \: x = \frac{9}{4} [/tex]
[tex]\sf \: x = 2\frac{1}{4} [/tex]
..
2x - 1
= 2(9/4) - 1
= 9/2 - 1
= 9/2 - 2/2
= 7/2
= 3 ½
