7x - 3y = 37
2x - y = 12
You can eliminate y by multiplying both sides of equation 2 by minus 3 and then add:
7x - 3y = 37
-6x + 3y = -36
x = 1
substitute x =1 into either equation and solve y
2(1) -y =12
-y = 10
y = -10

The elimination method is useful when you can eliminate one of the variable terms from an equation by adding or subtracting another equation?
True
How is the multiplication or division property of equality used in the elimination method and are the properties always needed?
If you multiply or divide an equation by any non-zero number, the two sides of the equation remain equal. This property is almost always needed for solving equations in which the variables have coefficients other than 1.
Solve by the elimination method x 9y 13 -x 2y -2?

Four steps to the elimination method?
There are four steps in an algebraic elimination problem. These steps are: to find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve. hi
How do you find a solution for a linear equation?

What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.
Is th answer in elimination method is same with substitution method?
Yes
