c. multipy equations
d. divide them

post your attempts

Answer 2

i really don't know how to do this.

Answer 3

a. add together
3-4x + -7x +4

combine terms and what do you get?

Answer 4

-11x+7

Answer 5

absolutely :)

now lets subtract
3-4x - (-7x +4)

Answer 6

3x+1

Answer 7

close but you are getting it
3 - 4 = -1

so it is 3x - 1
got it?

Answer 8

now lets multiply them

Answer 9
