Answer:
x = 1/4
y = 5 2/4
Step-by-step explanation:
Given two equations
1. 10x + 3y = 19
2. y = 2x + 5
Substitute 2x + 5 for y in the first equation
We have
10x + 3y = 19
10x + 3(2x + 5) = 19
Expand the bracket
10x + 3 X 2x + 3 X 5 = 19
10x + 6x + 15 = 19
16x + 15 = 19
Subtract 15 from both sides to eliminate 15 on the left
16x + 15 - 15 = 19 - 15
16x = 4
Divide both sides by 16 to isolate x
16x/16 = 4/16
x = 1/4
Now, substitute 1/4 for x in either equation to get y.
Using equation 2 , we have
y = 2x + 5
= 2(1/4) + 5
= 2/4 + 5
LCM of the denominator is 4.
Divide the LCM by the denominators and multiply the results by the numerators. Also, the LCM becomes the denominator of the results
Therefore
= 2 + 20/4
= 22/4
y= 5 2/4
x = 1/4 , y = 5 2/4

Answer:
7 cans
Step-by-step explanation:
You will first have to divide 480 by 4
The anwser is 480 ÷ 4 = 120
Then you will have to 840 ÷ 120 = 7
<h2>
The answer is 7 cans </h2>
It is what it is, everything going okay?
-Distribute the number outside the parenthesis into all the numbers within.
-Move the numbers with an "x" attached to it to one side and the numbers without an "x" to the other. be sure to change signs as you do (positive to negative, negative to positive)
-subtract or add the numbers on each side together
-divide the number attached to the "x" on both sides (ex. 7x=14, you divide 7)
- you get your answer (x=......)
