Answer:
[tex]x=46[/tex]
Step-by-step explanation:
[tex]20 + (5+7)=x-14[/tex]
[tex]20+12=x-14[/tex]
[tex]32=x-14[/tex]
Take [tex]x-14[/tex] on the other side of the 'equal to' sign and 32 on the other side so that the variable remains on the right side
[tex]x-14=32\\[/tex]
[tex]x=32+14[/tex]
[tex]x=46[/tex]
