Multiply the coefficients and the powers of 10 with each other:

The numeric part simply yields

As for the powers of 10, you have to add the exponents, using the rule

So, we have

So, the final answer is

<span>2/3 (x-7)= -2
x - 7 = -2 * 3/2
x - 7 = -3
x = -3 + 7
x = 4</span>
Just look at the line and see how many times it goes up it is just like rise over run it is simple
Replace the letters with their given values:
6(6) - 8 / 4
Do the multiplication:
36-8 / 4
Subtract:
28/4
Divide to get the final answer :7
Answer = 7
