To solve the equation, it is necessary to isolate the unknown variable "x" first. This is done as shown below:
2x - 3 = 15
Adding 3 to both sides of the equation:
2x - 3 + 3 = 15 + 3
2x = 18
Dividing 2 from both sides:
2x/2 = 18/2
x = 9

Hello!
To solve this, find the cost of a single light bulb first, by dividing 9 / 5.
9 / 5 ==> 1.80
One light bulb is $1.80
Now, multiply 1.80 by 7.
1.80 * 7 = 12.6
7 light bulbs cost $12.6
Hope this helps! ☺♥
