An easy 1: If 12y + 7 = 10, solve 4y. Can u do it?

If you mean "solve FOR y" then the answer is -\n12 y = 10-7 =3\ny = 3/12 = 1/4\n\nIf you meant "solve 4y (i.e. find the value of 4y)" then the answer is (similar technique to the previous one)-\n4y = 4*(1/4) = 1

2*4y*3y-4x*7y=24y-4y*7y\n\nDo your order of operations. There are no brackets, parentheses, or exponents; skip directly to multiplication and division.\n\n24y^2-28xy=24y-28xy\n\nThen clear one side, making it equal to zero.\n\n24y^2-28xy-24y+28xy=0\n24y^2-24y=0\n\nThen, factor.\n24y(y-1)=0\n\nNow, y can equal 0 or 1.\n\n24*0(0-1)=0\n24*1(1-1)=0\n\nThe value of x is irrelevant.

Start with \n\n    4x + 9y = 24\n\nsubstitute the value of y from the second equation:\n\n    4x + 9(-x/3 + 2) = 24\n--> 4x -3x + 18 = 24\n--> x = 24 - 18\n--> x = 6\n\nand now y can be computed,\n\n    y = -6/3 + 2\n--> y = 0

Well, let's check if y=4.\nJust replace y with 4\n4(4) + 2(4) = 24\n16 + 8 = 24\n24 = 24 \nThis is equation is true, so you are correct.
