Maybe try dividing by 300 and timesing by 1000?
<h3><u>The first number, x, is equal to 7.</u></h3><h3><u>The second number, y, is equal to 2.</u></h3>
x + 2y = 11
2x + y = 16
We can subtract 2y from both sides of the first equation to get a value for x.
x = 11 - 2y
Because we have a value for x, we can plug it into the second equation.
2(11 - 2y) + y = 16
Distributive property.
22 - 4y + y = 16
Combine like terms.
22 - 3y = 16
Subtract 22 from both sides.
-3y = -6
Divide both sides by -3.
y = 2
Now that we have a value for y, we can plug it into either equation to solve for x.
x + 2(2) = 11
x + 4 = 11
Subtract 4 from both sides.
x = 7
Form an equation using the information given
-4x - 6x = -20
simplify
-10x = -20
then solve by dividing by -10
x = -20/-10
x = 2
Answer:
The two numbers are 100 and 10
Step-by-step explanation:
Let's call the two numbers x and y.
Add 7 to both sides of the first equation to isolate x:
Substitute:
Hope this helps!
If (3)
x+y
=81 and (81)
x−y
=3, then the values of x and y are 17/8 and 15/8
