X=1 1/3 is that helpful because I don’t know if it’s right
Marry will pay in one year
(11,000*5)/100=550 dollars
550*4(years)=2200 dollars in total
15 x 45 = 675
45 x 135 =6075
For this case, what we are going to do is use the following property:
Multiply an equation by a scalar.
In this case, the scalar will be:
k = -2
We have then that equation 2 will be:
k * (4x + y) = k * 1
-2 * (4x + y) = - 2 * 1
-8x-2y = -2
Answer:
The property that justifies this manipulation is:
Multiply an equation by a scalar.
