Question

18 – 12 + x = 10 What value of x makes the equation true? * explanation plz

Answer 1

x = 4

Explanation:

18 – 12 + x = 10

Combine like terms on the left side: 18 - 12 = 6

6 + x = 10

Subtract 6 from both sides.

x = 4

Answer 2

x = 4

Explanation:

Solve for x:

x - 12 + 18 = 10

Hint: | Group like terms in x - 12 + 18.

Grouping like terms, x - 12 + 18 = x + (18 - 12):

x + (18 - 12) = 10

Hint: | Evaluate 18 - 12.

18 - 12 = 6:

x + 6 = 10

Hint: | Isolate terms with x to the left hand side.

Subtract 6 from both sides:

x + (6 - 6) = 10 - 6

Hint: | Look for the difference of two identical terms.

6 - 6 = 0:

x = 10 - 6

Hint: | Evaluate 10 - 6.

10 - 6 = 4:

Answer: x = 4
