Help 7 is the way its supposed to be done and I need help on 9 5-2 substitution intro worksheet
solve each system by substitution

Just tell koda to adjust the number of shapes himself.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
