What is the answer to 7b-15=5b-3

2 answers:

7 0

First you move -15 over which makes it 7b=5b+12
then you move 5b over so then its 2b=12
divide b=6

7 0

7b - 15 = 5b - 3
7b - 5b = -3 + 15
2b = 12
b = 6

Answer:

x = -7/5

Step-by-step explanation:

If we square both sides of the equation, we get:

$\sqrt{x^2-3x-6}=x-1\\ (\sqrt{x^2-3x-6})^2=(x-1)^2\\x^2-3x-6=x^2-2x+1\\$

Then, solving for x, we get:

$x^2-3x-6=x^2-2x+1\\-3x-6=2x+1\\-6-1=2x+3x\\-7=5x\\\frac{-7}{5}=x$

So, x is equal to -7/5
