Question

How do I write a system of equations with the solution (4,-3)?

Answer 1

First, write any system of 2 linear equations you like on the left side. For example:
3x - 2y =
4x + 3y =
Now, find the right side by replacing x = 4 and y = -3 in the 2 equations you wrote. Watch out the sign of -y.
3(4) - 2(-3) = 12 + 6 = .....
4(4) + 3(-3) = .......
