Answer:

                   a = -2

Simplifying 5 + -2(4a + 1) + 3a = 13 Reorder the terms: 5 + -2(1 + 4a) + 3a = 13 5 + (1 * -2 + 4a * -2) + 3a = 13 5 + (-2 + -8a) + 3a = 13 Combine like terms: 5 + -2 = 3 3 + -8a + 3a = 13 Combine like terms: -8a + 3a = -5a 3 + -5a = 13 Solving 3 + -5a = 13 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -5a = 13 + -3 Combine like terms: 3 + -3 = 0 0 + -5a = 13 + -3 -5a = 13 + -3 Combine like terms: 13 + -3 = 10 -5a = 10 Divide each side by '-5'. a = -2

How do you solve 5-X=-6-3X/2
zlopas [31]
<span> 5-X=-6-3X/2

First: You would get rid of your fraction by multiplying each side by two.
You would get: 2(5-x)=-6-3x > which equals 10-2x=-6-3x
Next: You would combine like terms, but we are going to do your x's first. You would add your -3x to both sides which makes it a positive.
You would get: 10-x=-6
Next: What you would do is subtract 10 on both sides of the equal sign.
You would get: -x=-16
Last: You would divide by -1 on each side of the equal sign to get your x alone.
Your answer would be: x=16

zlopas [31]

<u><em>Explanation</em></u>

On Monday, the bank account balance was -$12.58

B.  The bank charges a $25 fee for paying a check on a negative balance. So, the balance in your checking account after this fee =(18.14-25)dollar= -6.86 dollar

C.   For bringing your account balance back up to $0 after the fee, the money need to deposit =[0-(-6.86)]dollar =6.86 dollar.
