Answer:
x = 6
Explanation:
7(x - 4) = 14
Expansion
7 times x = 7x
7 times -4 = -28
7x - 28 = 14
Collect like terms, add 28 to both sides of the equation
7x - 28 + 28 = 14 + 28
7x = 42
Divide both sides by the coefficient of x which is 7
7x/7 = 42/7
x = 6
To check that x = 6 is the solution to the equation, we substitute the value of x = 6 into the equation
7(x - 4) = 14
7(6 - 4) = 14
7(2) = 14
