In order to solve using elimination, we need to be able to get rid of one variable, so that we can solve for the other. We need to subtract these two equations given from one another, or multiply the bottom equation by a negative and add them together.
(-5x + 6y = 8) - (-5x + 4y = 2)
(-5x + 6y = 8) + (5x - 4y = -2)
0x + 2y = 6
2y = 6
y = 3
Now that we know the value of one variable, we can take that value and plug it back into one of the original equations and solve for the value of the other variable.
-5x + 6y = 8
-5x + 6(3) = 8
-5x + 18 = 8
-5x = -10
x = 2
The solution to this system of equations is (2, 3).
Hope this helps!! :)
The answer of this question is<u> 24 toy trains.</u>
<u>Step-by-step explanation:</u>
Given,
Jerry gave away 15 trains .
Jerry left with 9 trains .
Jerry total brought toy trains = given away toy trains + left with toy trains
Total toy trains = 15 + 9
Total toy trains = 24
<u>Jerry brought a total of 24 toy trains.</u>
Your answer is 506.44.
multiply 662 x .10 now minus that answer from 662 to get 595.80
now multiply that by .15
now minus that by 595.80
gives you 506.43
Answer:
1,2, and 3
Step-by-step explanation:
Side = 8m
He increases length by 2m and reduces width by 2m
(a.) New dimensions will be -
Length = 10m and Width = 6m
(b.) Area = length x breadth (or width)
here we will use the special product (x+y) (x-y)
length = (x+y) and width = (x-y)
area = (8+2) x (8-2)
8^(2) - 2^(2)
= 60
