Explanation Procedure used: Solving system of equation by Substitution method: (1) Solve either of the equations for one variable in terms of the other. (If one of the equations is already in this form, you can skip this step.) (2) Substitute the expression found in step 1 into the other equation. (3) Solve the equation containing one variable. (4) Back-substitute the value found in step 3 into one of the original equations and find the value of the remaining variable. (5) Check the solution by substituting in one of the system of given equations”. Calculation: Consider the given equation as follows. 3 x + 5 y = 26 (1) x + 2 y = 10 (2) By using the above procedure, solve the system of equations. Step 1: Isolate the variable y to obtain the value of x from the equation (2). x + 2 y = 10 x + 2 y − 2 y = 10 − 2 y ( Solve for x by subtracting 2 y on both sides ) x = 10 − 2 y Step 2: Substitute 10 − 2 y for x in the equation (1). 3 x + 5 y = 26 3 ( 10 − 2 y ) + 5 y = 26 Here, the variable x is eliminated. Step 3: Solve the above equation
