Isolate y term: First, we want to isolate the term containing y on one side of the equation.20=−15+(117)yAdd 15 to both sides to move the constant term to the left side.20+15=(117)y35=(117)y
Solve for y: Now, we need to solve for y by getting rid of the fraction.To do this, we multiply both sides of the equation by the reciprocal of 117, which is 711.35 * 711 = (117)y * 711135 * 711 = y
Multiply by reciprocal: Perform the multiplication on the left side.(35×11)/7=y385/7=y
Perform multiplication: Now, divide 385 by 7 to find the value of y.385/7=55y=55
