Substitution And Elimination Worksheets

Apply the addition property of equality to equations (3) and (4) to eliminate y. This process is called solving a system by elimination. 1) y = 6x − 11 −2x − 3y = −7 (2, 1) 2.

Your Students Will Also Encounter Systems Of Equations Featuring The Distributive Property, Variables On Both Sides Of The Equation, And Like Terms.

Here, we have added line numbers to the equations, just to be able to reference each equation. None of the equations need to be manipulated, just plug it in. Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations.

{ X + Y = −9.

Rewrite both equations in the form ax + by = c, changing equations (1) and (2) to (3) and (4). Now when we have the value of x we can substitute the value in the first equation and find out the value of y. A few decimals and negative numbers are thrown in for good measure.
