Ann = 3 CD's
Ann = 2x-3
5 = 2x-3
x= CD's bob has
5 = 2x-3 is the equation
to solve
add 3 to each side
8 = 2x
divide by 2
x =4
bob has 4 CD's, ann has 5
360 - 20 + 2x = 360
340 + 2x = 360
2x = 20
x = 10
Answer:
16
Step-by-step explanation:
group the first 2 terms into (8*8) and the second two into (8*6). this gets you 8*8-8*6 which can be grouped into 8*2 which is 16
Terms: Binomial
Degree: Linear
19x-15 = 15x -7
4x = 8
x =2
19(2) -15 = 23
15(2) -7 = 23
