WebSimultaneous equations are sometimes indicated by a long curly bracket to link them together. The method for solving simultaneous equations with variable \(x\) and \(y\) is: First rearrange one equation to obtain an expression or a value for \(x\). The rearranged equation may be \(x\) = a number, or it may be an expression where \(x\) = a ... Webx = D x D, x = D x D, y = D y D. y = D y D. Step 5. Write the solution as an ordered pair. Step 6. Check that the ordered pair is a solution to both original equations.
