Add 5/7 on both sides.
It'll cancel out the negative 5/7, and it will make the x variable only equal to one number (Well, a mixed number.)
Answer:
no
Step-by-step explanation:
Pretty good, How about you
7y = 84
y = 84 /7
= 12
So, y =12
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
Plug 8 into one of the equations and you will find how many chairs total there are.
9(8) + 3 = 75
There are 75 chairs total
