Answer:

[tex]\text{a) } 2(x + 3) = x -4[/tex]

[tex]2x+6= x -4[/tex]

[tex]2x+6-6= x -4-6[/tex]

[tex]2x= x -10[/tex]

[tex]2x-x= x -x-10[/tex]

[tex]x=-10[/tex]

[tex]\text{b) } 4(5x - 2) = 2(9x + 3)[/tex]

[tex]20x - 8 = 18x+ 6[/tex]

[tex]20x - 8+8 = 18x+ 6+8[/tex]

[tex]20x = 18x+ 14[/tex]

[tex]20x-18x = 18x-18x+ 14[/tex]

[tex]2x = 14[/tex]

[tex]$\frac{2x}{2} =\frac{14}{2} $[/tex]

[tex]x=7[/tex]
