Substitution And Elimination Systems Of Equations Math 1010 2 1 The substitution method. to solve a system of two linear equations in two variables, solve one of the equations for one of the variables. substitute the expression for the variable chosen in step 1 into the other equation. There are three ways to solve systems of linear equations: substitution, elimination, and graphing. let’s review the steps for each method. substitution. get a variable by itself in one of the equations. take the expression you got for the variable in step 1, and plug it (substitute it using parentheses) into the other equation.
Substitution And Elimination Math Showme Substitution method: this method involves isolating for one variable (x y) of line 1 then substituting that variable into line 2. this will allow you to isolate and solve for the other variable (y x). once you have the x and y coordinates, you then have the solution which is the point of intersection between the two lines. line 1: y = 6 – 2x. This algebra video tutorial explains how to solve systems of equations by elimination and how to solve systems of equations by substitution with 2 variables . If there was a number in front of the y i would need to divide and that would cause fractions. so i will take the equation 3x – y =11 and solve for y. you will get y = 3x – 11. now we need to substitute this into the other equation for y: − 2 x 5 (3 x − 11 ) = − 16 now solve for x. 2 x 15 x −. 13 x − 55 = −. 1 emoji logic puzzles these logic puzzles are a fun way to get students solving systems without even realizing it! they would also be fun warmups or as emergency sub plans during this unit. 2 solving systems of equations by graphing pennant solving systems by graphing is the best place to start the unit.
