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
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
What is 3x plus 2y equals 6 solve for y?
3x+2y=6 2y=-3x+6 y=-1.5x+3
How do you solve the system of equation by substitution x plus 2y-2 3x plus 4y6?
If you mean x+2y = -2 and 3x+4y = 6 then by solving the simultaneous equations by substitution x = 10 and y = -6
