Answer:

x=-3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(2x+8)=10

(5)(2x)+(5)(8)=10(Distribute)

10x+40=10

Step 2: Subtract 40 from both sides.

10x+40−40=10−40

10x=−30

Step 3: Divide both sides by 10.

10x/10= −30/10

x=−3

Answer:

D. x=-3

Step-by-step explanation:

First of all, it's an equation (=), not an inequality (>). D is the only option that shows the result of an equation :)

Anyway, here you go:

Simplify the equation using PEMDAS. Expand using the distributive property:

[tex]5(2x)+5(8)=10\\\\10x+40=10[/tex]

Use inverse operations to isolate the variable. Subtract 40 from both sides, canceling out the positive 40 on the left:

[tex]10x+40-40=10-40\\\\10x=-30[/tex]

Isolate the variable using inverse operations. Divide both sides by 10, canceling the 10 out on the left:

[tex]\frac{10x}{10} =\frac{-30}{10} \\\\x=-3[/tex]

The value of x is -3. The correct answer is (D).

:Done
