Answer 2

Given,

The expression: 15 (x-9)-2 (x-12)+5(x+6)=0.

To find,

The value of x.

Solution,

The value of x will be 4.5.

We can easily solve this problem by following the given steps.

According to the question,

We have the following expression:

15 (x-9)-2 (x-12)+5(x+6)=0

Now, multiply the numbers outside the brackets into the brackets:

15x-135-2x+24+5x+30 = 0

Adding or subtracting the numbers on one side and the terms with the same variables on the other side:

(15x-2x+5x)+(-135+24+30) = 0

(20x-2x)+(-135+54) = 0

18x-81 = 0

Moving 81 from the left-hand side to the right-hand side will result in the change of the sign from minus to plus:

18x = 81

x = 81/18

x = 4.5

Hence, the value of x is 4.5.
