We got the value of by solving the given equations and by reduction method.
<h2>
What is reduction method?</h2>
The reduction or elimination approach includes using arithmetic operations between equations to produce equivalent equations with fewer unknowns that are simpler to analyze and evaluate.
Given equations are
.........(1)
...........(2)
We need to find the value of
Simplifying the given equation (2) and we get
................(3)
Now, substitute the equation (3) in equation (1) and we get
Substitute the value of x in equation (3), we get
Now adding the values of x and y, we get
Therefore, the value of .

Answer:
(4.5,0) x intercept
(0,-1) y intercept
Step-by-step explanation:
f(x) = log (2x+1) -1
y = log (2x+1) -1
To find the x intercept, set y = 0 and solve for x
0 = log (2x+1) -1
Add 1 to each side
1 = log (2x+1)-1+1
1 = log (2x+1)
Raise each side to the power of 10
10^1 = 10^ log(2x+1)
10 = 2x+1
Subtract 1 from each side
10-1 = 2x+1-1
9 = 2x
Divide by 2
9/2 =2x/2
4.5=x
The x intercept is 4.5
(4.5,0)
To find the y intercept, set x = 0 and solve for y
y = log (1) -1
y = 0 -1
y = -1
The y intercept is -1
(0,-1)

Step-by-step explanation:
hello I hope this helps you
a²b is the same thing as ba²
b and a are two separate variables lets pretend a is 2 and b is 3
2² * 3 = 4 * 3 = 12
3 * 2² = 3 * 4 = 12
this is the commutative property of multiplication
