# 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

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
