7x+15=12x+5
Step #1 Subtract 12 from both 7x and 12x on the left and on the right. This is because we only want one x, and combining like terms is not an option therefore we must eliminate.
7x+15= 12x+5
-12 -12
-5x+15=5
Step #2 subtract 15 from both sides.
-5x+15=5
-15 -15
-5x=-10
Step #3 Divided both sides by coefficient which in this case is -5. We want x by itself
x=2

Really hope this made sense. I can help with other problems if you’ll like

What is x if <br> Show your working<br> 4x+5=5x-1
weeeeeb [17]

Answer:

x=6

Step-by-step explanation:

First, add 1 on both sides

4x + 5 = 5x -1

     +1           +1

4x+6 =5x

Then, subtract 4x on both sides

4x+6 =5x

-4x      -4x

6=x

So, x equals 6

Hope this helps! :)

Jasmine purchased a laptop worth $1,500 in 2007. It loses its value by %32 each year. What is the value of the laptop in 2010? R
Lunna [17]

Answer:

$471.65

Step-by-step explanation:

-The value of the laptop after each year is calculated by the formula:

P_t=P_o(1-d)^t

where:

P_t is the value at time t

P_o is the initial value

d is the rate of depreciation

t is the time

#We substitute the values to solve for the value after 3 years(2010-2007=3):

P_t=P_o(1-d)^t\\\\=1500(1-0.32)^3\\\\=\$471.65

Hence, the value of the laptop in 2010 is $471.65
