In this equation, b is the variable that we need to isolate. To do that, divide both sides of the equation by the value in front of the b, -86. Since anything divided by itself is 1, and 1 times X is X, we can isolate b.

-86 x b = 43

(-86) / (-86) x b = 43 / (-86) = 1/(-2)

**b = - 1 / 2**

-86 x b = 43 -------eq(i)

The value of b is unknown here therefore we should isolate b

-86 x b = 43

-86b/-86=43/-86 (dividing both sides by 86)

**b=-0.5**

In order to be sure input the value of b into eq(i)

-86 x b = 43

-86 x -0.5=43

43=43

LHS=RHS

-86 x b = 43

-86b = 43

divide by -86

b = 43/-86

b = -1/2 or -.5

-86 x b = 43

Rewrite equation

- -86(b)=43

Since '(-86)(b)' is multiplication, what is the opposite operation for it? (Division)-- To isolate the variable 'b', divide both sides by -86.

- `(-86b)/-86 = 43/-86`

Simplify

- b=`-1/2`

-86 x b = 43

-86b = 43

divide by -86

b = 43/-86 simplify

b = -1/2 or -.5

-86 x b = 43

b=43/-86 divide both sides by -86

b=-1/2 after you simplify the fraction

-86 x b = 43

In this equation, we have to try to get " b " alone. In order to do that divide by -83 on both sides.

By dividing by -83 on both sides your equation should be

**b = -43/86 **simplify this fraction

By simplifying your fraction would be

**b = 1/2 **which is your answer

-86b=43

So you want to isolate the b by itself in order to figure out its value. To do this we mist get rid of the -83 by dividing both sides by -83. So you get

b= -43/86

Then you simplify. Resulting in

b=- 1/2. As your answer

-86 x b = 43

-86b=43

-86b/-86b=43/-86

b=.5

Sorry I meant to say b=-.5

When you are solving equations you have to think of a balance scale what you do to one side you must to the other side of the equal sign. The goal is to ge the variable (b) alone on one side of the equal sign.

-86 x b = 43

b= 43 / -86

b= -0.05
