Question

Write a two column proof for the following statement.

“Given that 2( -x + 4) = 3 , prove that x = 5/2.

Pleasee help as quick as you can

Answer 1

Answer:

Statement:

$2(-x+4)=3$

Reason:

If we want to prove this statement, we have to isolate $x$ from the equation:

$2(-x+4)=3$

Applying the distributive property:

$-2x+8=3$

Grouping similar terms:

$-2x=3-8$

$x=\frac{-5}{-2}$

Finally:

$x=\frac{5}{2}$
