Answer:
Step-by-step explanation:
Look for one or more common factors. Note here that 5 is a factor of 10x and also a factor of 5y, so 5 is a common factor of 10x+5y, and so ...
10x+5y = 5(2x + 1y) = 5(2x + y)
Repeat: dividing both terms of 10x+5y by the common factor 5 yields
5(2x + 1y) = 5(2x + y)
Answer:
4x10=40 10
Step-by-step explanation:
10 people in each row. 4 rows of people. 10+10+10+10
Use the expression for y in the second equation.
.. 3x +4(3 -(1/2)x) = 1
.. 3x +12 -2x = 1
.. x +12 = 1
.. x = -11
Answer:
(5, 18) and (-3, 2)
Step-by-step explanation:
We have two equations:
Let's eliminate y by setting the two equations equal:
Move all the terms to one side:
Factor:
Solve for x:
x - 5 = 0
x = 5
OR
x + 3 = 0
x = -3
Plug each of these values of x into any of the two original equations:
y = 8 + 2 * 5 = 8 + 10 = 18
y = 8 + 2 * (-3) = 8 - 6 = 2
The solutions are (5, 18) and (-3, 2).
