If we are given or come up with a statement of 4 = 4, then the equation is true, This is because the left hand side and the right hand side are equal. Solving <span>y − 2x = 11 and y + 2x = 9, we just add the two equations to yield 2y = 20 or y equal to 10. x is equal to -1/2. The coordinates are (-1/2, 10)</span>
