How do you solve 3x - 4y equals 4?

i dont know what you are trying to solve for, but if you are solving for x and y. u have to...... 3x-4y=4 x= 4/3..... 1.33 y=4/-4...... -1


How do you solve y-3x 15?

To solve the equation ( y - 3x = 15 ) for ( y ), you need to isolate ( y ). You can do this by adding ( 3x ) to both sides of the equation, resulting in ( y = 3x + 15 ). This expresses ( y ) in terms of ( x ).


How do you solve 3x-4y 2x-y?

To solve the expressions (3x - 4y) and (2x - y), you need to establish what you're looking to do with them, such as setting them equal to each other or solving for one variable in terms of the other. If you want to find their intersection, set (3x - 4y = 2x - y) and solve for (x) and (y). Rearranging gives (x - 4y + y = 0), or (x - 3y = 0), leading to (x = 3y). Substitute this back into either original expression to find specific values for (x) and (y).


What is the answer to 3x plus y equals 9?

Solve for x:3x + y = 9 is the same as -3x + 9 = ySince you now know the equation for y you can plug it into the first equation:3x + (-3x + 9) = 9After solving, you will see that x cancels out and that 9 = 9.Solve for y:3x + y = 9 is the same as 3 - y/3 = xSince you now know the equation for x you can plug it into the first equation:3(3 - y/3) + y = 9After solving, you will also see that y cancels out and that 9 = 9.The Answer:There are actually two posibble answers:1.) y = 9 and x = 0If you plug the numbers in then you will get 3(0) + (9) = 9The answer is 9 = 92.) y = 0 and x = 3If you plug the numbers in then you will get 3(3) + (0) = 9This will also give you the answer 9 = 9


What is 3x-2y equals 6 solve for y?

3x-2y=6 -2y=-3x+6 y=1.5x-3
