What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

-4x - 5 + 2x = -11 is an equation.

We have,

-4x - 5 + 2x = -11

Combine like terms.

-2x - 5 = -11

Add 5 on both sides.

-2x = -11 + 5

-2x = -6

Divide both sides by -2.

x = 3

Thus,

The value of x is 3.

Answer:

x = 3

Step-by-step explanation:

-4x - 5 + 2x = -11

add 5 to both sides and cancel the -5 on the left

-4x + 2x = -6

combine -4x and 2x

-2x = -6

divide both sides by -2 and cancel the -2 on the left

x = 3

Answer:

216c³

Step-by-step explanation:

8 yellow = 2³ (sides = 2 cubes)

Green added to cover yellow, making it (2+2)³ = 4³

Red added to cover green, making it (4+2)³ = 6³

Total cubes = 6³ = 216 cubes

Each cube has a volume = c³

Volume of the final cube = 216c³ units³

An equation is shown below: 5(2x - 8) + 15 = -15

Write the steps you will use to solve the equation and explain each step.

Answers

5 (2×-8)+15= -15

distribute the 5 into (2×-8) and it becomes

10x-40 + 15 = -15

add -40 and +15

10× - 25 = -15

add +25 to both sides

10x= 10

divide both sides by 10

x = 1

5(2x-8)+15=-15 -15 in both sides 5(2x-8)=-30 /5 2x-8=-6 +8 2x=2 /2 x=1 I hope it helps
