Lets do a simple two step equation
For example,
2x-8=12
Our main goal is to get the X value alone.
In order to do this, We will subtract 8 from both sides.
Our equation will now look like:
2x=20
In order to get the X alone here, We have to divide 2x by 2 in order to cancel out the 2 out. This means that since we divided by 2 on one side, we have to do it on the other.
Our equation now looks like:
x=10

Answer:
450 students
Step-by-step explanation:
Let s = number of students
1/2 are Americans 1/2s are Americans
s -1/2s = number of students left
1/2 s = number of students left
1/3 of the students left are Europeans
1/3 (1/2s) = 1/6s are Europeans
The rest are Australians = 150
Students = Americans + Europeans + Australians
s = 1/2s + 1/6s + 150
Combine like terms
s = 1/2*3/3 *s + 1/6s +150
s = 3/6s + 1/6s +150
s = 4/6s + 150
Subtract 4/6s from each side
s -4/6s = 150
6/6s - 4/6s = 150
2/6s = 150
1/3s = 150
Multiply each side by 3
3* 1/3s = 150*3
s = 450
There are 450 students
Answer:
There are 200 centimetres in 2 metres. Therefore, 80 centimetres is equal to 80/200 x 100 = 40 percent of 2 metres
I’m not sure if this is right. but wouldn’t it be 0 if he spent the remaining amount of money on supplies for an art project?
