Question

What's the answer when solving by elimination?

Answer 1

0 = -36

# the statement is false

Explanation:

-42y = 7x + 6

-6x = 36y

*simplify move the term

-7x - 42y = 6

-6x - 36y = 0

*multiply both side

42x + 252y = -36

-42 x -252y = 0

*elimi.ate one variable by adding the equation

0 = -36

* the statement is false.

Answer 2

Answer: the system of equations has no solution

Explanation:

`-42y=7x+6\ \ \ \ (1)\\-6x=36y\ \ \ \ \ \ \ (2)\\`

Divide both parts of the equation (2) by -6:

`x=-6y\ \ \ \ \ \ (3)`

Substitute equation (3) into equation (1):

`-42y=7(-6y)+6\\-42y=-42y+6\\0\\eq 6`

Hence, the system of equations has no solution
