attashe74 [19]
<h2>The bond will be worth in total after 10 years is =$1,950</h2>

Step-by-step explanation:

Given,

Nora invested $1,500 in at a bond simple interest rate of 3%

here P= $1500 R= 3% and t = 10year

Simple interest(I) = \frac{P\times R \times t }{100}

                           =$ \frac{1500\times 3 \times 10}{100}

                           =$ 450

<h3>The bond will be worth in total after 10 years is = $1,500+ $450</h3><h3>                                                                                      =$1,950</h3>

-3x + 3y = 4<br> -x+ y = 3
Natalka [10]

Answer:

No solution

Step-by-step explanation:

-3x + 3y = 4

-x + y = 3

<u>Solve the equation for x:</u>

<u>Move the variable to the right side and change its sign</u>

-x + y = 3

-x = 3 - y

<u>Change the signs on both sides of the equation</u>

-x = 3 - y

x = -3 + y

<u>Substitute the given value of x into the equation -3x + 3y = 4</u>

-3x + 3y = 4

x = -3 + y

-3(-3+y)+3y=4

<u>Solve the equation for y</u>

-3(-3+y)+3y=4

y = 0

There is no solution for y.

And since there's no solution for y, the system has no solution.
