Is x=7 a solution to the following equation: -(7-4x)=9 yes or no and explain why

no, x=4

Explanation:

First, solve parentheses:

-(7-4x)= -7+4x

-7+4x=19

Then add 7 to both sides:

4x=16

Then divide by 4:

x=4

Hope this helps! Pls mark brainliest if correct:)

Explanation:

Neil will have the following amount after ten years.

Simple interest is calculated using the formula,

I= p x r x t

where I= interest, P= principal amount, r = interest rate, t is time

for Neil interest will be= $15,000 x 3/100 x 10

=$15,000 x 0.03 x 10

=$4500

Neil will have principal + interest amount

=$4,500 + $15,000

=$19,500

John invested in a compound interest account.

The amount after ten years will be

The formula for compound interest is

FV = PV × (1+r)^n

where FV = Future Value

PV = Present Value

r = annual interest rate

n = number of periods

After ten years, John will have

Fv= $15,000 x (1 + 3/100)^10

Fv= $15,000 x (1.03)^10

FV =$15,000 x 1.34391

Fv = $15,158.75

John will be able to clear his mortgage.
