Answer 3

Answer in detail. Solve the equation x × 2 + 28 = 100 using the properties of equality.

To solve the equation, we need to isolate x on one side of the equation. We can use the properties of equality to manipulate the equation and maintain the balance. The properties of equality are:

- Reflexive property: a = a - Symmetric property: If a = b, then b = a - Transitive property: If a = b and b = c, then a = c - Addition property: If a = b, then a + c = b + c - Subtraction property: If a = b, then a - c = b - c - Multiplication property: If a = b, then a × c = b × c - Division property: If a = b and c ≠ 0, then a ÷ c = b ÷ c

Here are the steps to solve the equation using the properties of equality:

- Step 1: Subtract 28 from both sides of the equation using the subtraction property. This will eliminate the constant term on the left side.

x × 2 + 28 - 28 = 100 - 28

Simplify:

x × 2 = 72

- Step 2: Divide both sides of the equation by 2 using the division property. This will eliminate the coefficient of x on the left side.

(x × 2) ÷ 2 = 72 ÷ 2

Simplify:

x = 36

- Step 3: Check the solution by substituting x = 36 into the original equation and see if both sides are equal.

x × 2 + 28 = 100

36 × 2 + 28 = 100

Simplify:

72 + 28 = 100

100 = 100

The solution is correct because both sides are equal.

Therefore, the solution of the equation is x = 36.
