1. Choose the best method to solve by looking at the way the equations are set up for you: Elimination method
2. Using the best method, how could you get the x variables to cancel out? Multiply the first equation by 2 and the second equation by -3.
3. After you complete step 2, what would your top equation be? 6x + 8y = 96
4. Line them up and add the equations:
6x + 8y = 96
6x + 2y = 60
By adding the equations together, the x variables cancel out:
10y = 36
Now you can solve for y:
y = 36/10
y = 3.6
To find the value of x, substitute the value of y back into one of the original equations:
3x + 4(3.6) = 48
3x + 14.4 = 48
3x = 48 - 14.4
3x = 33.6
x = 33.6/3
x = 11.2
Therefore, the solution to the system of equations is x = 11.2 and y = 3.6.
