find the value of x in 6x+14=42
Answers
Step-by-step explanation:
6x+14=42
6x = 42 - 14
6x = 28
x = 28/ 6
x = 4 . 67
Step-by-step explanation:
Simplifying
4x + 6x + -14 = 42 + -4x
Reorder the terms:
-14 + 4x + 6x = 42 + -4x
Combine like terms: 4x + 6x = 10x
-14 + 10x = 42 + -4x
Solving
-14 + 10x = 42 + -4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
-14 + 10x + 4x = 42 + -4x + 4x
Combine like terms: 10x + 4x = 14x
-14 + 14x = 42 + -4x + 4x
Combine like terms: -4x + 4x = 0
-14 + 14x = 42 + 0
-14 + 14x = 42
Add '14' to each side of the equation.
-14 + 14 + 14x = 42 + 14
Combine like terms: -14 + 14 = 0
0 + 14x = 42 + 14
14x = 42 + 14
Combine like terms: 42 + 14 = 56
14x = 56
Divide each side by '14'.
x = 4
Simplifying
x = 4
