Let the two numbers be represented by x and y respectively.
Then x + y = 23, and x - y = 5.
Solve this system of linear equations for x and y. Start by rearranging them vertically:
x + y = 23
x - y = 5
--------------- Combining the two equations eliminates y:
2x = 28.
Then x = 14. If x = 14, then 14 + y = 23, and y = 9..
The solution is (14, 9); that is, x = 14 and y = 9.
Answer:
x=54
Step-by-step explanation:
Answer:
f(2) = 9(2) and f(0) = g(0)
Step-by-step explanation:
As in the expression f(x) = g(x), the values in parentheses need to be the same for both f( ) and g( ). That is only the case for the first answer choice.
Answer:

Step-by-step explanation:
First, find the LCM and multiply through:

The LCM will cancel out the denominators (note that braket symbolizes Multiplication):
:3(2x-1) +4(x)=24
:6x-3+4x=24
Group like terms:
6x+4x=24+3
10x=27
Divide through by 10 to eliminate the coefficient of x

: x=
