Answer:
The value of
is 17-18x and
is -7-18x.
Step-by-step explanation:
It is given in the question functions f(x) as 3x+2 and g(x)=5-6x.
It is required to find
and
.
To find
, substitute g(x) for x in f(x) and simplify the expression.
To find
, substitute f(x) for x in g(x) and simplify the expression.
Step 1 of 2
Substitute g(x) for x in f(x) and simplify the expression.

Step 2 of 2
Substitute f(x) for x in g(x) and simplify the expression.

Keep the denominators the same and subtract the numerators. So for example in your example:
7/8 - 3/8
Leave the 8 alone. Subtract 3 from 7.
7 - 3 = 4
So answer is:
4/8
Sometimes they may have to simplify the answer, and in this case, 4/8 could be simplified to 1/2
X<9
The answer is x<9 because you first subtract 4 from both sides then divide both sides by -3. Which then would give you 9.
