Make sure you set the two expressions equal to each other. 5.3 (4x-2.6) = 21.2x

NOw that that's done, distribute 5.3 to 4x and 2.6. 21.2x-13.78=21.2x Now you get all the x's on one side of the equation. But since they are the same number and subtracting one from the other would result in an answer of 0x. So the answer would be - 13.78. I hope this is correct!
