Solve for x in the equation 2x^2 + 3x - 7 = x^2 + 5x + 39

Graph red beads cost $1 an ounce and gold beads cost $3 an ounce. juanita wants to purchase a 12-ounce mixture of red and gold beads that she can sell for $2 an ounce. the solution of the system shows the number of beads needed for juanita to break even. x + y = 12, x + 3y = 24 how many ounces of red beads will juanita buy to break even? how many ounces of gold beads will she buy?

If y varies as x, and y=8 as x=4 what will be the value of y if x=2
