Answer :
So first I seperate both equations:
4(-87+4)
=-348+36
=-312
11=8(n-3)-1
= 11=8n-24-1
= 11=8n-25
Join them together and u get:
11=8n-25-312
= 11=8n-337
Move 11 to the right:
8n=-11-312
= 8n=-348
348/8n
=43.5n
4(-87+4)
=-348+36

11=8(n-3)-1
= 11=8n-24-1
= 11=8n-25
Join them together and u get:
11=8n-25-312
= 11=8n-337
Move 11 to the right:
8n=-11-312
= 8n=-348
348/8n
=43.5n
