Elena and Lin are trying to solve 12x+3=72x+5. Describe the change they each make to each side of the equation.

Elena’s first step is to write 3=72x−12x+5.
Lin’s first step is to write x+6=7x+10.

Answer:

No Solution

Step-by-step explanation:

12x + 3 = 72x + 5

subtract 12x from both sides

end up with

3 = 72x - 12x + 5

subtract 12x to 72x

3 = 60x + 5

-5 from both sides

-8 = 60x

since x is a bigger number the answer would be NO SOLUTION

12x + 3 = 72x + 5

I do not understand lins logic

x + 6 = 7x + 10

subtract 6 from both sides

x = 7x + 4

move 7x to the other side

7x = 4

divide 7

x = 0.5

Also wrong because I get how lin got that answer

My way

12x + 3 = 72x + 5

-12 x from both sides

3 = 60x + 5

+5 to other side

8 = 60x

if the x was on the other side it would make sense

but it is not so the Answer is NO SOLUTION

Hope this Helped :)

The required solution of the given equation is given as -0.03.

Given that,
Elena and Lin are trying to solve 12x+3=72x+5. we have to describe the change they each make to each side of the equation.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given equation,
12x+3=72x+5
Add and subtract 12x and 5 on both sides,
12x - 12x + 3 - 5 = 72x - 12x + 5 - 5
-2 = 60x
x = -2/60
x = 0.03

Thus, the required solution of the given equation is given as -0.03.
