NettetIf the two lines have two different slopes, then they will intersect once.Therefore, the system of equations has exactly one solution.; If the two lines have the same slope but different y y y y-intercepts, then they are parallel lines, and they will never intersect.Therefore, we can say that the system of equations has no solutions.; If the … NettetThe method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable. Here is how it works.

If the coefficient of any variable is 1, which means you can easily solve for it in terms of the other variable, then substitution is a very good bet. psychology today subscription priceNettetIt is the most familiar method for solving systems of linear equations. It consists of two phases: the elimination phase and the backward substitution phase. The first phase has the purpose, as indicated in the previous table, to transform the equations from the form Ax=b to that of immediate solution Ux=c. hosting costNettetSubstitute that into the second equation. 3 (y+8)-y=16. Distribute the 3. 3y+24-y=16. add like terms. 2y+24=16. subtract 24 from both sides. 2y=-8. divide by 2 y=-4. Now that you know y=-4, plug that in the first equation. x=-4+8. x=4 ( 11 votes) Show more...
