in either equation and solve for x. X + 4y = 1 Therefore the point of intersection is (-3, 1) X + 4(1) = 1. X + 4 = 1. X = -3 . Example 2: Use substitution to solve the system of equations. If the system does not have one solution tell whether it has infinitely many solutions or no solution. Y = 2x + 1. 2y = 4x +2. Step 1 - Choose a variable to ...

by rearranging the equation. Multiplying out the expression on the left side of the equation yields 3 x plus 3 y equals y. Then, subtracting 3. y from both sides of the equation gives 3 x, equals negative 2 y. Finally, dividing both sides of this equation by 3. y (note that . y. does not equal zero) gives the fraction . x over y
