Answer:
x = (2c - 3b + 5) / (c - b).
Step-by-step explanation:
c(x - 2) - 5 = b(x - 3)
cx - 2c - 5 = bx - 3b Bring the terms in x to left side:-
cx - bx - 2c - 5 = -3b Bring other terms to right side:-
cx - bx = 2c - 3b + 5
x(c - b) = 2c - 3b + 5 Divide both sides by c - b:-
x = (2c - 3b + 5) / (c - b).
D=(b^2)-(4)(a)(c)
36-(4)(-2)(13)= 139
The answer is false
if you solve both sides it says that 627.25 is less than 3.714 which isn't correct because 627.25 is obviously greater than 3.714

Answer:
- 15 = -3c +12
- -3n +8 = -7
- 5z -40 = 10
- 3.4s -35 = 50
Step-by-step explanation:
Usually, you're asked to "simplify" an equation, meaning that you eliminate parentheses and combine like terms. Asking for "simplest form" suggests something different. The simplest form is the form that has the variable equal to a constant--the solution, in other words.
We suspect you want the <em>simplified form</em>, but since you asked for the <em>simplest form</em>, that is here, too.

1. 15=-3(c-1)+9
15 = -3c +3 +9
15 = -3c +12 . . . . . simplified form of the given equation
-1 = c . . . . . . . . . . "simplest" form
__
2. 2(1.5n+4)-6n=-7
3n +8 -6n = -7
-3n +8 = -7 . . . . . . simplified form of the given equation
n = 5 . . . . . . . . . . . "simplest" form
__
3. 2(z-20)+3z=10
2z -40 +3z = 10
5z -40 = 10 . . . . . . simplified form of the given equation
z = 10 . . . . . . . . . . "simplest" form
