Answer:
x=4,y=3
Step-by-step explanation:
x=19-5y if we transpose equation 2 for x.
Plug that into equation 1
4(19-5y)+3y=25
76-20y+3y=25
76-25=17y
51=17y
y=3
Plug y=3 into equation 2
x+5(3)=19
x=19-15=4

The solution of x in -6 + 3x - 9x^2 = -16 is 
<h3>How to solve the equation?</h3>
The equation is given as:
-6 + 3x - 9x^2 = -16
Add 16 to both sides
10 + 3x - 9x^2 = 0
Rewrite as:
9x^2 - 3x - 10 = 0
Solve for x using the quadratic formula
So, we have:
Evaluate
Hence, the solution of x in -6 + 3x - 9x^2 = -16 is

Answer:
A. x = -2
Step-by-step explanation:
A spreadsheet is a suitable tool for making a chart like this.
The values of f(x) and g(x) are the same for x = -2. That is, f(-2) = g(-2), so x=-2 is the solution to f(x)=g(x).
