Question

What is the value of x?
4x - 9 = 27

Answer 1

4x - 9 = 27
+ 9
4x = 36
36 / 4
x = 9

Answer 2

thanks

Answer 3

Yup ;)

Answer 4

What is the value of x?
6( - 3 - x) - 2x = 14

Answer 5

Solve for x:
6 (-3-x)-2 x = 14
Distribute 6 over -3-x.
6 (-3-x) = -18-6 x:
-18-6 x-2 x = 14
Combine like terms in -2 x-6 x-18.
-6 x-2 x = -8 x:
-8 x-18 = 14
Isolate terms with x to the left hand side.
Add 18 to both sides:
(18-18)-8 x = 14+18
Look for two terms that sum to zero.
18-18 = 0:
-8 x = 14+18
Evaluate 14+18.
14+18 = 32:
-8 x = 32
Divide both sides by a constant to simplify the equation.
Divide both sides of -8 x = 32 by -8:
(-8 x)/(-8) = 32/(-8)
Any nonzero number divided by itself is one.
(-8)/(-8) = 1:
x = 32/(-8)
Reduce 32/(-8) to lowest terms. Start by finding the GCD of 32 and -8.
The gcd of 32 and -8 is 8, so 32/(-8) = (8×4)/(8 (-1)) = 8/8×4/(-1) = 4/(-1):
x = 4/(-1)
Simplify the sign of 4/(-1).
Multiply numerator and denominator of 4/(-1) by -1:
Answer: |
| x = -4
