8(- 4x - 3) = - 2 - 6(1x + 6x)
- 32x - 24 = - 2 - 42x
10x = 22
x = 22/10
or
x = 2 1/5.

First, put all the x's on one side and everything else on the other. Like this;
-32x - 24 = -2 -6x - 36x (distributive property)
-32x +6x + 36x = -2 + 24 (grouping the like-terms)
10x = 22 ( adding the like-terms)
x = 22 / 10 = 2.2
Hopefully this will help

8(-4x - 3)= -2 - 6(1x+6x)
=> -32x - 24 = -2 - 6x - 36x
=> -32x - 24 = -2 - 42x
=> 2 - 24 = - 42x + 32x
=> -22 = -10x
=> x = 22/10 = 11/5

First Distribute the Equation:
-32x - 24 = -2-6x+36x^2
-26x - 24 = -2 + 36x^2
36x^2+26x-22 = 0
Divide by two both sides
18x^2 + 13x - 11 = 0
'Then you can factor this multiple ways, but I use the quadratic equation.
Once factored you get:
(-11-9x)(1-2x) = 0
-11-9x = 0
-11 = 9x
x = -11/9
1-2x = 0
2x=1
x=1/2
So final answer
x= -11/9 and 1/2

I divided the 3/2 and got 1.5 and substituted 1.5 for 3/2 and got the following answer and then will give you the steps-- you can substitute (3/2) or use (3/2) and get the same answer x= 8/3 or approximately 2.6666666666667 Step 1: Combine like terms and use the properties of equality to get teh variable on one side of the equals sign and the numbers on the other side. Remember to follow the order of operations 1.5(x+8)=6x Step 2: Multiply 1.5x+12=6x Step 3: Subtract 12 from both sides of the equation 1.5 x=6x-12 Step 4: Subtract 6x from both sides of teh equation Step 5: Divide both sides of the equation by -4.5, which is teh same as multiplying both sides by the reciprocal of the fraction x= 8/3 or approximately 2.6666666666667 Second way to do it same answer just not using the 1.5

8(-4x - 3)= -2 - 6(1x+6x)
- 32x -24 = -2 - 42x (multiple this with (-1))
32x + 24 = 2 + 42x
10 x = 22
x = 2.2

8(-4x-3) = -2-6(7x) combine x terms on RHS
-32x-24 = -2-42x distribute and simplify both LHS and RHS
10x-24 = -2 +42x to both sides
10x = 22 +24 to both sides
x= 22/10 = 11/5 divide both sides by 10

8(-4x - 3)= -2 - 6(1x+6x)
-32x -24 = -2 - 42x
10 x = 22
x = 22/10 = 11/5 = 2.2

-32x - 24= -2 -42x
10x=22
x=2.2 or 11/5
