What is the value x that makes the following equation true? -3x-6(2x+8)=-5x-35

es tiens que multiplication

x= -13/10

Step-by-step explanation:

First, distribute the -6.

-3x-6(2x+8)=-5x-35

-3x-12x-48=-5x-35

Combine Like Terms.

-15x-48=-5x-35

Add 48 to both sides to have 1 variable by itself.

-15x=-5x+13

Add 5x to both sides of the equation.

-10x=13

Divide by 10 on both sides to simplify.

Therefore, giving you -13/10 or -1.3 as a decimal.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
