Solve the system of two linear equations -3x - or why people minus 23 3x - 5y = 5 options - 5, 2 5, 2 - 5, - 2 5 - five, minus 2
To solve the system of equations -3x - 5y = -23 and 3x - 5y = 5, we can use the method of elimination.
Adding the two equations together, we get:
(-3x - 5y) + (3x - 5y) = -23 + 5
-10y = -18
Divide by -10:
y = 1.8
Now that we have the value of y, we can substitute it back into one of the original equations to solve for x. Using the second equation:
3x - 5(1.8) = 5
3x - 9 = 5
3x = 14
x = 4.67
Therefore, the solution to the system of equations is x = 4.67 and y = 1.8. The correct answer choice is 5, -2.
