3x(2x+3y)
1. find a common multiple of either sides of the + sign...
3x
2. put it outside the brackets...
3x( )
3. find what you have to multiply the rest equation by to get the number...
2x x 3x = 6x squared
3y x 3x = 9xy
4. put it in the brackets...
3x(2x+3y)
Hope this helps :)
Move the constant to the left-hand side by adding its opposite to both sides
The sum of two opposites equals
By 0
Answer : 2x+ 2y -3=0
The number of half page advertisements that Michael purchased is 4 while the full page advertisements is 11.
Let the number of half page ads be represented by h
Let the number of full page ads be represented by f.
Total number of advertisements = 15
h + f = 15 ....... (i)
h = 15 - f
Therefore, the system of equations to represent the situation will be:
60h + 100f = 1340 ........ (ii)
Put the value of h into equation (ii)
60(15 - f) + 100f = 1340
900 - 60f + 100f = 1340
Collect like terms
100f-60f = 1340-900
40f = 440
f = 11
The number of full-page advertisements that Michael purchased is 11.
Since h + f = 15
h + 11 = 15
h = 15 - 11
h = 4
The number of half page advertisements that Michael purchased is 5.
