Question

Use substitution to solve the system of linear equations. In your final answer, include all of your work.

y = 3x - 9
x - 1/3y = -3

Answer 1

he variable term is zero so, the equation has no-solution

Explanation:

Given as :

The two linear equation are

y = 3 x - 9 .........1

x -
`(1)/(3)` y = - 3 .........2

Now, , In substitution method we have to put the value of one variable from one equation into the other equation

Let put the value of y from eq 1 into eq 2

∵ x -
`(1)/(3)` y = - 3

Or, x -
`(1)/(3)` × ( 3 x - 9 ) = - 3

Or, x -
`(3 x)/(3)` +
`(9)/(3)` = - 3

Or, (x - x) + 3 = - 3

Or, 0 = - 3 + 9

Or, 0 = 3

∵ The variable term is zero so, the equation has no-solution Answer
