Capitolo 2, Problema 13
In Exercises 1–26, solve and check each linear equation. 7x + 4 = x + 16
Guida verificata passo dopo passo1
Start by writing down the given equation: \(7x + 4 = x + 16\).
To isolate the variable terms on one side, subtract \(x\) from both sides: \(7x - x + 4 = 16\).
Simplify the left side by combining like terms: \(6x + 4 = 16\).
Next, subtract 4 from both sides to isolate the term with \(x\): \(6x = 16 - 4\).
Finally, divide both sides by 6 to solve for \(x\): \(x = \frac{16 - 4}{6}\).
