If x is equal to 3 times open paren y plus w close paren minus 1 , what is the value of w in terms of x and y ?
A
w is equal to the fraction with numerator x plus 1 and denominator 9 yB
w is equal to x minus 3 y plus 1C
w is equal to the fraction with numerator x minus 3 y and denominator 3D
w is equal to the fraction with numerator x minus 3 y plus 1 and denominator 3Start with x = 3(y + w) - 1. Add 1 to both sides, then subtract 3y: 3w = x + 1 - 3y. Divide by 3 to get w = (x - 3y + 1)/3, which matches choice D.
