Question

Use the text box below to type all steps (showing all work, each step!) to explain (in words and with math!) whether or not x = -72 is a solution to x LaTeX: \div÷ 4 + 5 = 8.

Answer 1

x=-12

Explanation:

Given the expression we are to find the value of x;

Step 1; Rearrange the equation:

Step 2: subtract 5 from both sides of the equation:

Step 3: Find the value of x:

Hence the solution to the equation is 12 not -72

Answer 2

x = 12

Explanation:

Given the expression
`x / 4 + 5 = 8.` we are to find the value of x;

Step 1; Rearrange the equation:

`(x)/(4) + 5 = 8\\`

Step 2: subtract 5 from both sides of the equation:

`(x)/(4)+5-5 = 8-5\\(x)/(4) + 0 = 3\\(x)/(4) = 3\`

Step 3: Find the value of x:

`x = 4*3\\x = 12`

Hence the solution to the equation is 12 not -72
