15=2y-5
move -5 to the other side
sign changes from -5 to +5
15+5= 2y-5+5
15+5= 2y
20= 2y
divide both sides by 2
20/2= 2y/2
y= 10
Answer : y= 10
Answer:
6 is the answer
Step-by-step explanation:
Answer:
x=3; y=5
Step-by-step explanation:
y=x+2
y=3x-4
so x+2=3x-4
2x=6
x=3
because y=x+2
x=3
so y=3+2
=5
The initial value of the Greg`s home: $328,500. If his home is predicted to increase in value 4% each year, that means that the value will rise 1.04 times every year.
The predicted value after 30 years:
$328,500 * ( 1 + 0.04 ) ^30 =
= $328,500 * 1.04^30 =
= $328,500 * 3.2434 =
= $1,065,456.
Answer: The predicted value of his home in 30 years is $1,065,456.
Some number y has 7 subtracted off to get 15. We have y-7 = 15. To isolate y, we have to undo the "subtract 7" operation that happens to y. We have to add 7 to both sides.
y-7 = 15
y-7+7 = 15+7
y = 22 is the answer
