Answer:

-2x +4 = 20

Step-by-step explanation:

given

[tex] - 2x + 4 = 20[/tex]

by making x the subject, you need to subtract 4 from 20

thus

[tex] - 2x = 20 - 4[/tex]

[tex] - 2x = 16[/tex]

and also you need to divide through by -2

[tex] \frac{ - 2x}{2} = \frac{16}{ - 2} [/tex]

[tex]x = - 8[/tex]
