X=8

Answer 2

To find the values of x and y that satisfy the given system of equations:

1. Solve one of the equations for one variable in terms of the other variable. Let's solve the first equation for x: 6x - 5y = -12 6x = 5y - 12 x = (5y - 12)/6

2. Substitute this expression for x into the second equation. 4((5y - 12)/6) + 3y = 30

Multiply through by 6 to eliminate the fraction: 4(5y - 12) + 18y = 180 20y - 48 + 18y = 180 38y - 48 = 180 38y = 180 + 48 38y = 228 y = 228/38 y = 6

3. Substitute the value of y back into the expression for x. x = (5y - 12)/6 x = (5*6 - 12)/6 x = (30 - 12)/6 x = 18/6 x = 3

Therefore, the solution to the system of equations is x = 3 and y = 6.
