Isolate y term: First, we want to isolate the term containing y on one side of the equation.12−(72)y=30Subtract 12 from both sides to move the constant term to the right side.12−12−(72)y=30−12
Simplify equation: Now, simplify both sides of the equation.0−72y=18−72y=18
Get rid of fraction: Next, we want to solve for y by getting rid of the fraction. Multiply both sides by −27 to cancel out the fraction on the left side.\left(-\frac{\(7\)}{\(2\)}\right) \times \left(-\frac{\(2\)}{\(7\)}y\right) = \(18 \times \left(-\frac{7}{2}\right)
Solve for y: Simplify both sides of the equation.y=18×(−27)y=−63
