3/4z - 1/4z + 3 = 2/4z + 5
3/4z - 1/4z - 2/4z = 5 - 3
2/4z - 2/4z = 2
0 ≠ 2

<span>It has no solution.</span>
Answer:
It is the first one and for number 2 is 160 people total
2x=80
4x=160
You first see where it starts on the y axis. whether it be 1 or 2 or 3 or even 3. Than you look at the slope by counting from that point from the y axis going up and over until you reach a point. not a line a point. and if it's 3 up and one over than it's 3x. But it's for example it's 3 up and 2 over than it's 3/2x. Than you set up the equation as y= mx + b. m being the slope that you found. x just remains the same. and b is where the point started on the y axis
38.5 is equal to 38 1/2
38*2+1= 77, so the fraction in its simplest form is 77/2
You need a common denominator while subtracting because really a fraction is a division problem and you cannot do 4/5-8/9 it does not make sense as for multiplication you really just multiplying everything that is why it makes sense.
