Answer:
Step-by-step explanation:
-3.1+7-7.4x=1.5x-6(x-1.5)
We move all terms to the left:
-3.1+7-7.4x-(1.5x-6(x-1.5))=0
We add all the numbers together, and all the variables
-7.4x-(1.5x-6(x-1.5))+3.9=0
We calculate terms in parentheses: -(1.5x-6(x-1.5)), so:
1.5x-6(x-1.5)
We multiply parentheses
1.5x-6x+9
We add all the numbers together, and all the variables
-4.5x+9
Back to the equation:
-(-4.5x+9)
We get rid of parentheses
-7.4x+4.5x-9+3.9=0
We add all the numbers together, and all the variables
-2.9x-5.1=0
We move all terms containing x to the left, all other terms to the right
-2.9x=5.1
x=5.1/-2.9
x=-1+1/1.31818181818
THIS IS UR ANSWER... THANK YOUU
