Okay, so -9x = 3x-10 first we add ten to both sides 10-9x=3x next add 9x to both sides 10=12x now divide both sides by 12 10/12=x reduce 5/6 The check... -9 x (5/6) = -45/6 reduced is -15/2 3 x 5/6 = 15/6 15/6 - 10 = 15/6 - 60/6 = -45/6 or -15/2 Therefore we have the correct answer :D

44 = 9x +8 36=9x 4=x
9 x 27 equals 243

You can solve that equation for either x or y. To solve for y: Subtract 9x from both sides to get -4y=7-9x Divide both sides by -4 to get y=-(7-9x)/4 or -1.75+2.25x
9x-5x=4x, 7/4=1.75, x=1.75
