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

natulia [17]

In order to solve this problem, use sign conventions. Since deposit indicates cash inflow, that would take the positive sign. On the other hand, withdrawals take negative sign. We add these integers to the original balance. he solution is as follows:

$100 + $25 + $50 + $15 + (⁻$40) =<em> $150</em>
