To solve the system of equations algebraically, we have the following equations:
- 9x + 2y = 5
- y = 2x + 3
We can use substitution to solve this system. Since the second equation already expresses y in terms of x, we can substitute that expression into the first equation.
Substituting y from the second equation into the first gives us:
9x + 2(2x + 3) = 5
Now, simplify the equation:
9x + 4x + 6 = 5
Combine like terms:
13x + 6 = 5
Next, isolate x by subtracting 6 from both sides:
13x = 5 - 6
13x = -1
Now, divide by 13:
x = -\frac{1}{13}
Now that we have the value of x, we can substitute it back into the second equation to find y:
y = 2(-\frac{1}{13}) + 3
y = -\frac{2}{13} + 3
y = -\frac{2}{13} + \frac{39}{13}
y = \frac{37}{13}
So, the solution to the system of equations is:
x = -\frac{1}{13}, y = \frac{37}{13}
In conclusion, the points that satisfy both equations are (-1/13, 37/13).
