Since you know the value of "x", you can plug in the value for "x" in the equation.
[When an exponent is negative, you move it to the other side of the fraction to make the exponent positive.]
For example:
or 
or y³
x = -2
f(x) = 9x + 7
f(-2) = 9(-2) + 7 = -18 + 7 = -11
(idk if you should have it as a decimal or a fraction)
x = -1
f(x) = 9x + 7
f(-1) = 9(-1) + 7 = -9 + 7 = -2
x = 0
f(x) = 9x + 7
f(0) = 9(0) + 7 = 7
x = 1
f(x) = 9x + 7
f(1) = 9(1) + 7 = 9 + 7 = 16
x = 2
f(x) = 9x + 7
f(2) = 9(2) + 7 = 18 + 7 = 25
You need to determine the solution of f(x) = g(x)
Since you know f(x) = 9x + 7 and , you can plug in (9x + 7) for f(x), and (
) into g(x)
f(x) = g(x)
You can plug in each value of x into the equation
Your answer is x = 2 because when you plug in 2 for x in the equation, you get 25 = 25

Answer:
x = (-7)/5
Step-by-step explanation:
Solve for x:
3 (x - 6) - 8 x = 5 (2 x + 1) - 2
3 (x - 6) = 3 x - 18:
3 x - 18 - 8 x = 5 (2 x + 1) - 2
Grouping like terms, 3 x - 8 x - 18 = (3 x - 8 x) - 18:
(3 x - 8 x) - 18 = 5 (2 x + 1) - 2
3 x - 8 x = -5 x:
-5 x - 18 = 5 (2 x + 1) - 2
5 (2 x + 1) = 10 x + 5:
-5 x - 18 = 10 x + 5 - 2
Add like terms. 5 - 2 = 3:
-5 x - 18 = 10 x + 3
Subtract 10 x from both sides:
(-5 x - 10 x) - 18 = (10 x - 10 x) + 3
-5 x - 10 x = -15 x:
-15 x - 18 = (10 x - 10 x) + 3
10 x - 10 x = 0:
-15 x - 18 = 3
Add 18 to both sides:
(18 - 18) - 15 x = 18 + 3
18 - 18 = 0:
-15 x = 3 + 18
3 + 18 = 21:
-15 x = 21
Divide both sides of -15 x = 21 by -15:
(-15 x)/(-15) = 21/(-15)
(-15)/(-15) = 1:
x = 21/(-15)
The gcd of 21 and -15 is 3, so 21/(-15) = (3×7)/(3 (-5)) = 3/3×7/(-5) = 7/(-5):
x = 7/(-5)
Multiply numerator and denominator of 7/(-5) by -1:
Answer: x = (-7)/5
Answer:
Step-by-step explanation
Note that if x>2, then x+3>3+2=5. Then x+3>0. Recall that the absolute value function is defined as
Since x+3>0, we have that |x+3|=x+3
