On a architect's drawing of a house, 1 inche representa 1.5

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab

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.
