Solve:
X х
+6 - 2x = -6
3

x=69

Step-by-step explanation:

x+6−2x=−63

Step 1: Simplify both sides of the equation.

x+6−2x=−63

x+6+−2x=−63

(x+−2x)+(6)=−63(Combine Like Terms)

−x+6=−63

−x+6=−63

Step 2: Subtract 6 from both sides.

−x+6−6=−63−6

−x=−69

Step 3: Divide both sides by -1.

−x

−1

=

−69
