Answer:
x=7
Step-by-step explanation:
5x=35
5x/5=35/5
x=7
You can using any equation you want to solve for one of the variables. For instance, if you want to solve for x you turn one of the equations so y is by its self
<span>
2x + 3y = 5
4x - y =3
I am going to use </span>4x - y =3
-y = -4x + 3
y = 4x -3
Now you can substitute 4x - 3 for y in 2x + 3y = 5 and solve for x
2x + 3y = 5
2x + 3(4x - 3) = 5
Answer:
g(x)=(x+4)-5
Step-by-step explanation:
I don't explain well but bascially translated to the left is adding 4 in the x with a paranthesis. Right is negative
We need to compute for the length of each trophy given that one trophy is 5 inches wider than the other.
Let x be the length of the first trophy.
Let x+5 be the length of the second trophy
The solution is shown below:
x + (x + 5) = 17
x + x + 5 =17
2x =17 -5
2x = 12
x = 12/2
x=6 (for the first trophy)
x + 5 = 6+5 = 11 (for the second trophy)
The first trophy is 6 inches wide while the second trophy is 11 inches wide.
In this digital age, online payment services are added services that will make bill payments easier.
Online stores and businesses have cropped up and their market is worldwide. To facilitate easy exchange of goods and services, online payment services are offered.
Online payment services benefit both the seller and the buyer.
