-1 + 4x=3x +3<br> Solve for x ?

docker41 [41]

Answer:

$x = 4$

Step-by-step explanation:

1. Regroup terms.

$4x - 1 = 3x + 3$

2. Add 1 to both sides.

$4x = 3x + 3 + 1$

3. Simplify 3x + 3 + 1 to 3x + 4.

$4x = 3x + 4$

4. Subtrect 3x from both sides.

$4x - 3x = 4$

5. Simplify 4x - 3x to x.

$x = 4$

Therefor, the answer is, x = 4.

Find the unpaid balance on the debt after 5 years of monthly payments on $190,000 at 3% for 25 years

NNADVOKAT [17]

Answer:

$114,000

Step-by-step explanation:

Use formula

$I=P\cdot r\cdot t,$

where

I = interst

P = principal

r = rate

t = time

First, find the interst for 25 years:

I = unknown

P = $190,000

r = 0.03 (3% as decimal)

t = 25

$I_{25}=190,000\cdot 0.03\cdot 25=142,500$

Now find the interest for 5 years:

I = unknown

P = $190,000

r = 0.03 (3% as decimal)

t = 5

$I_5=190,000\cdot 0.03\cdot 5=28,500$

The unpaid balance is

$I=I_{25}-I_5=142,500-28,500=114,000$
