Answer:

Y = 7

Step-by-step explanation:

You would add 4 to both sides to cancel out the -4. That leaves y by itself equaling 7.

Answer: x = 0

Step-by-step explanation:

4x − 3 + x = 7x − 3

Step 1: Simplify both sides of the equation.

4x − 3 + x = 7x − 3

4x + −3 + x = 7x + −3

(4x + x) + (−3) = 7x − 3(Combine Like Terms)

5x + −3 = 7x − 3

5x − 3 = 7x − 3

Step 2: Subtract 7x from both sides.

5x − 3 − 7x = 7x − 3 − 7x

−2x − 3 = −3

Step 3: Add 3 to both sides.

−2x − 3 + 3 = −3 + 3

−2x = 0

Step 4: Divide both sides by -2.

-2x/-2 = 0/-2

x = 0

Answer:

The value of f(g(3) = 1,008

Step-by-step explanation:

Step:-1

Given f(x) = $3 x ^ 2 + 2 x$

and g(x) = 3x+9

h(x) = 12+x

Given g(x) = 3x+9

put x =3

g(3) = 3(3)+9

g(3) = 18

Step :-(2)

f(g(3)) = f(18)

f(g(3) = 3(18)^2 +2(18) (since f(x) = $3 x ^ 2 + 2 x$ )

= 1,008

Final answer:-

The value of f(g(3) = 1,008
