Mrs. Deihl wants to solve the system shown using the elimination method. Which is the best way to begin? 10x - 7y = -13

-20x + 14y = 26

Question 1 options:

Isolate the x variable in the second equation.

Multiply each term in {10x -7y = -13} by 2 and add it to the other original equation.

Multiply each term in {10x -7y = -13 } by –2 and add it to the other original equation.

Add the corresponding sides of each equation.

Multiply each term in {10x -7y = -13} by 2 and add it to the other original equation.

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

I hope this is what you want:

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
