Answer:
-3
Step-by-step explanation:
firstly, -3/12 is not in the simpliest form so we have to simplified it:
-3/12 / 3 = -1/4, now we got:
= (-6*(-1/4)*-4*5) / 10
The upper part of the equation: (-6*(-1/4)*-4*5) can be simplified as:
((-6*-1*-4*5) / 4) / 10
= (-120/4)/10
= -30 / 10
= -3

Solution:
Given equation is
.
To solve the equation by step by step.
Step 1: Given

Step 2: Combine like terms together.
Plus symbol changed to minus when the term goes from right to left (or) left to right of the equal sign.

Step 3: Subtract the fractions in the left side.

⇒ 
Step 4: Divide both side of the equation by 3, we get


Hence, the answer is
.
-2/3x+9=4/3x-3 original problem add 2/3x to both sides
9=6/3x-3 simplify 6/3 to 2 and add 3 to both sides
12=2x divide both sides by 2
x=6
hope that helps
