|4x+3|=9+2x if we square both sides, we can eliminate the absolute values signs...
16x^2+24x+9=81+36x+4x^2 subtract the right side from both sides
12x^2-12x-72=0 now we can factor
12(x^2-x-6)=0
12(x^2+2x-3x-6)=0
12(x(x+2)-3(x+2)=0
12(x-3)(x+2)
So:
x= -2 or 3
Answer:
9/2 or 4.5
Step-by-step explanation:
15/4x6/5 = 3/2x3 = 9/2
<h2>
Hello!</h2>
The answer is:
The x-coordinate of the solution to the system of equations is:

<h2>
Why?</h2>
We can solve the problem writing both equations as a system of equations.
So, we are given the equations:

Then, solving by reduction we have:
Multiplying the first equation by 2 in order to reduce the variable "x", we have:


Now, substituting "y" into the first equation, to isolate "x" we have:

Hence we have that the x-coordinate of the solution to the system of equations is

Have a nice day!
