Upload it to your Compute Solve for x: 7(x + 3) = 4(x + 9)

x=5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7(x+3)=4(x+9)

(7)(x)+(7)(3)=(4)(x)+(4)(9)(Distribute)

7x+21=4x+36

Step 2: Subtract 4x from both sides.

7x+21−4x=4x+36−4x

3x+21=36

Step 3: Subtract 21 from both sides.

3x+21−21=36−21

3x=15

Step 4: Divide both sides by 3.

3x

3

=

15

3

x=5

i pretty sure it is

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
