3b + 300 = 6b
300 = 3b
b = 100
Answer:
To solve the answer, you can do it in 2 ways:
1) you could take the square root on both sides and solve for x
OR
2)you could multiply 3x-5 times itself and subtract 19 on both sides and use the grouping or quadratic formula method to find x.
Hope it helps.
Answer:
B
Step-by-step explanation:
I used the quadratic formula
Answer:
Add 3 to both sides
Property: Addition property of equality
Step-by-step explanation:
Action: Add 3 to both sides.
⇒ x - 3 = 12
(cancel out)+ 3 + 3
------------------------ -----
x = 15
The property used:
- Addition property of equality.
→ equation is true and the same #is added to each side the resulting equation is true. for any #s a,b,c,if a=b then a+c=b+c.
Answer:
x-y
Step-by-step explanation:
Combine like terms
2/3x + 1/3x - 3y + 2y
1x - 1y
x - y
