Answer:

[tex]x = 4[/tex]

Step-by-step explanation:

[tex]AD = BC[/tex]

[tex]8x - 12 = 20[/tex]

[tex]8x = 20 + 12[/tex]

[tex]8x = 32[/tex]

[tex] \frac{8x}{8} = \frac{32}{8} [/tex]

[tex]x = 4[/tex]

to be sure

[tex]8x - 12 { = }^{?} 20[/tex]

[tex]8 \times 4 - 12 { = }^{?} 20[/tex]

[tex]32 - 12 { = }^{?} 20[/tex]

[tex]20 = 20[/tex]
