Answer:

Here we can go for trial and error,

Taking x=6

So equation will be 6*6-18 which gives 18

and is not equal to 54

So it's, not 6

Trying 12

6*12-18

Which is 54 and so correct answer is x=12

What is the solution to the equation 5x = 40?

Dima020 [189]

To find X, we can divide 5 into 40.
40 divided by 5 is 8.
Now we can do 5 x 8. That is 40.

X=40

OR we can do it another way.
40 divided by 5 is 8.
Cross out 5 divided by 5.

Now we have 8. Still.
X is 8
