Questions: Solve the equation. .7 x+7.65=10.8

Solution Steps

To solve the equation \(0.7x + 7.65 = 10.8\), we need to isolate the variable \(x\). First, subtract 7.65 from both sides of the equation to get \(0.7x\) by itself. Then, divide both sides by 0.7 to solve for \(x\).

Starting with the equation: \[ 0.7x + 7.65 = 10.8 \] we subtract \(7.65\) from both sides: \[ 0.7x = 10.8 - 7.65 \] Calculating the right side gives: \[ 0.7x = 3.15 \]

Next, we divide both sides by \(0.7\): \[ x = \frac{3.15}{0.7} \] Calculating this results in: \[ x = 4.5 \]
