Solve the equation 3(2a-b)+4(2-5a)=18?

To solve the equation 3(2a-b)+4(2-5a)=18, we first distribute the coefficients:

6a - 3b + 8 - 20a = 18

Combine like terms:

-14a - 3b + 8 = 18

Subtract 8 from both sides:

-14a - 3b = 10

Now, we have a system of equations:

-14a - 3b = 10

We cannot solve this system without more information or another equation.
