Question

How many solutions are there to the equation below?

4(x - 5) = 3x + 7

Answer 1

Answer: There could be 3 or 4 or maybe 2 to this equation

Explanation:

Answer 2

There is only one solution to the equation which is x=27

Explanation:

4(x - 5) = 3x + 7

All we need to do is find the value of x

We will start by opening the bracket, we will do this by multiplying 4 by all the variables in the bracket

4x - 20 = 3x + 7

Subtract 3x from both-side of the equation

4x -3x -20 = 3x -3x + 7

4x-3x-20 = 7

x - 20 = 7

Add 20 to both-side of the equation

x- 20 + 20 = 7+ 20

x = 27

There is only one solution to the equation
