If a consistent linear system of … WebWhen two equations have the same slope, they will have either no solution or infinite solutions. By putting both equations into the form , we get: and. With the equations in this form, we can see that they have the same slope, but different y-intercepts. Therefore, there is no solution to this system. WebCombining like terms yields. x - 2 = 10. Adding 2 to each member yields. x-2+2 =10+2. x = 12. To solve an equation, we use the addition-subtraction property to transform a given equation to an equivalent equation of the form x = a, from which we can find the solution by inspection. Example 3 Solve 2x + 1 = x - 2. lacedscorpion instagram
