2 pounds of clay for each pot A and 3 pounds of clay for each pot B. We're using all of 26 pounds of clay so we obtain the equation: 2A + 3B = 26 Similarly, 2 bottles of paint for A and 1 bottle of paint for B. We're using all of 14 bottles, s…

1. c/7 + 2 = 1 iff (isolate the term with the variable, c/7) c/7 = -1 iff c = -7 2. 6 - 3a/2 = -6 iff -3/2 a = -12 iff (multiply both side by the reciprocal of coefficient, which is -2/3) a = 8 3. 75 + 7x = 2x iff (move variable to on…

y = kx^3 x is doubled so replace x with 2x then compare the result. k(2x)^3 = k(8x^3) = 8kx^3 = 8y We see that y increases by factor of 8.
