Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

What is x3+3x2−16x−48 divided by x−1?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
