Question

Complete the two-column proof.

Given: x/6 + 2 =15
Prove: x = 78
X/6 + 2 =15 a. __________
x/6= 13 b. __________
x = 78 c. ___________

Answer 1

The equation you start with is the given equation.
x/6 + 2 = 15 a. Given

The next step in solving this equation is subtracting 2 from both sides.
x/6 = 13 b. Subtraction Property of Equality

Lastly, to cancel out the denominator, multiply both sides of the equation by 6.
x = 78 c. Multiplication Property of Equality

Answer:
a. Given
b. Subtraction Property of Equality
c. Multiplication Property of Equality

Answer 2

The value of x is 78 and this can be determined by using the arithmetic operations. Where a) given equation, b) subtract by 2, and c) multiply by 6.

Given :

Equation  --  $\rm \dfrac{x}{6}+2=15$

The following steps can be used in order to evaluate the given equation:

Step 1 - The arithmetic operations can be used in order to evaluate the given equation.

Step 2 - Write the given equation.

$\rm \dfrac{x}{6}+2=15$

Step 3 - Subtract 2 from both sides in the above expression.

$\rm \dfrac{x}{6}+2-2=15-2$

$\rm \dfrac{x}{6}=13$

Step 4 - Now, multiply 6 on both sides in the above expression.

$\rm \dfrac{x}{6}\times 6=13\times 6$

x = 78
