Consider the sequence of steps to solve the equation:
5(x - 3) = 7x 2
Step 1 ⇒ 10(x - 3) = 7x
Step 2 ⇒ 10x - 30 = 7x
Step 3 ⇒ 3x - 30 = 0
Step 4 ⇒ 3x = 30
Step 5 ⇒ x = 10
Identify the property of equality which yields Step 5.
I'm thinking division

The 1st problem is that the solution is not correct
The 2nd problem is that you seem to be using x as a variable on the left side, and as a multiplication sign on the right.
or is 7x2 supposed to say 7x^2 ?
In step #1, you multiplied the left side by 2, but divided the right side by 2
5(x - 3) = 7x 2
5x + 15 = 14
5x = -1
x = -1/5
