3-93.

For the following equations, solve for $x$. Check your solution, if possible. Record your work.

1. $3x−7=3x+1$

Add $7$ to both sides.

$3x−7=3x+1$
$\ \ \ +7\ \ \ \ \ \ +7$

Subtract $3x$ from both sides.

$3x=3x+8$
$−3x−3x$

$0=8$

The statement is not true; therefore, the answer is: No Solution.

1. $−2x−5=−4x+2$

Follow the steps in part (a).

1. $2+3x=x+2+2x$

Follow the steps in part (a).

Any number.

1. $−(x−2)=x+2$

How does the negative sign in front of the parentheses change what is inside?
