Answer:
x = -6
Step-by-step explanation:
Simplifying
5x + 7 = 3x + -5
Reorder the terms:
7 + 5x = 3x + -5
Reorder the terms:
7 + 5x = -5 + 3x
Solving
7 + 5x = -5 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
7 + 5x + -3x = -5 + 3x + -3x
Combine like terms: 5x + -3x = 2x
7 + 2x = -5 + 3x + -3x
Combine like terms: 3x + -3x = 0
7 + 2x = -5 + 0
7 + 2x = -5
Add '-7' to each side of the equation.
7 + -7 + 2x = -5 + -7
Combine like terms: 7 + -7 = 0
0 + 2x = -5 + -7
2x = -5 + -7
Combine like terms: -5 + -7 = -12
2x = -12
Divide each side by '2'.
x = -6
Simplifying
x = -6
The answer is 7 because 12+9 is 21 and 21-14 is 7.
This is a good expression. x+2. This is simple. x is the variable and 2 is the constant.
2/5=24/60 because you have to make the denominators the same in order to do the problem. Which means...
5/12=25/60
Afterwards just add them together. 24/60 + 25/60 which equals 49/60. You can't simplify so the answer is 49/60 students.
Answer:
-2 x^2 (x - 3) thus the answer is c:)
Step-by-step explanation:
Factor the following:
6 x^2 - 2 x^3
Factor -2 x^2 out of 6 x^2 - 2 x^3:
Answer: -2 x^2 (x - 3)
