Answer/Step-by-step explanation:

Given:

Emiliano thinks x = 40 is the solution to the equation 1/2x = 80

Note:

An equation is the statement that equalizes two mathematical expressions.

An expression is the combination of variables and constants connected with mathematical operations.

Solve:

Substituting the value of x, in the equation

1/2(4) = 80

20 ≠ 80

Thus, it isn't satisfied. Hence, Emiliano's answer is wrong.

Correct Way to Solve;

Multiply both sides by 2

2 ·
(1)/(2)x = 80 · 2

Simplify

x = 160
