Answer:

x = 7

Step-by-step explanation:

Step by step solution :

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

3x - 21 = 3 • (x - 7)

Equation at the end of step 1 :

Step 2 :

Equations which are never true :

2.1 Solve : 3 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : x-7 = 0

Add 7 to both sides of the equation :

x = 7

One solution was found :

x = 7

6=2(y+2) solve for y

ipn [44]

Answer:

y=1

Step-by-step explanation:

6=2(y+2) distribute your first 2 outside of the (_)

6= 2y+4 then subtract 4 from both sides

Then you will have 2= 2y divide both sides by the 2 from 2y

After you have 1=y

Plug the new y value back in and you will have

2(1+2)= (_) always goes first so you will have 3

2(3) when you have a number beside of a (_) you multiple and receive the answer that this equals 6 to check yourself

What should be done to solve the following equation?

Maslowich

The equation C -7 - 3/4 = 0 is an algebraic equation

To solve the equation we (a) add 7 and 3/4 to both sides of the equation

<h3>How to determine the action on the equation?</h3>

The equation is given as:

C -7 - 3/4 = 0

Make C the subject of formula by adding 7 and 3/4 to both sides of equation

C = 7 + 3/4

Now, we can solve for C

Hence, to solve the equation we (a) add 7 and 3/4 to both sides of the equation
