Question

Jeremy wrote this equivalent equation to solve for x=-11y-140 Which of these equations might have been Jeremy’s original equation? Check all that apply. y + 7x = 23, y + 11x = 140, 2x – 22y = –140, 3x + 33y = –420, x + 140 = –11y

Answer 1

Answer:

out of the 5 option 4 and 5 are correct

Step-by-step explanation:

Answer 2

Equivalent equation of $x= -11y-140$ are $3x + 33y = -420,$ and $x + 140 = -11y$.

What is equation?

" Equation is defined as relation between variables and numbers using the sign of equality."

According to the question,

Given equation,

$x=-11y-140$

Equivalent equation of given equation are,

$3x + 33y = -420,$

Simplify it  we get,

$3x= -33y -420\\\\x = -11y-140$

And

$x + 140 = -11y$

Simplify it we get,

$x= -11y -140$

which is same as given equation.

Hence, equivalent equation of $x= -11y-140$ are $3x + 33y = -420,$ and $x + 140 = -11y$.
