Question

Elena Says x is a number that makes Equation A true but does not make Equation B true.

Equation A : 13 - 5x = 48
Equation B : 5x = 35

Write a convincing explanation as to why this is true​

Answer 1

See below

Explanation:

13 - 5x = 48 Subtract 13 from both sides

-5x = 35

-5x = 35 is the not the same as 5x = 35

-5x = 35 Divide both sides by -5

x = -7

5x = 35 Divide both sides by 5

x = 7

7 and -7 are not the same solution. They are two different numbers.
