Question

What is the solution to the following
equation?
7x - 20 = -41
-
a). X=-3
b). X=3

Answer 1

Answer:

A). X = -3

Step-by-step explanation:

Step 1: Add 20 to both sides.

• $7x-20+20=-41+20$
• $7x=-21$

Step 2: Divide both sides by 7.

• $7x/7 = -21/7$
• $x=-3$

Step 3: Check if solution is correct.

• $7(-3)-20=-41$
• $-21-20=-41$
• $-41=-41$
