-2x+5=13 you subtract 5 away from +5 and this cancels out. you then do the same to the other side by taking 5 away from 13 therefor you get 8. Now you have -2x=8, take -2x and divide it into 8 and you get 4.
3x+8 = 5x+10 Take 3x away from both sides: 8 = 2x + 10 Take 10 away from both sides: -2 = 2x Divide both sides by 2: -1 = x
take this for example 4/5 divided by 7/8.you have to keep the first fraction the same 4/5 and reverse 7/8 into 8/7 take the numerator and switch it with the denominator. then you multiply 4 times 8 equals 32 and 5 times 7 equals 35 so the answer is 32/35! BY : AVERY LEVIN

1 minus 5/8 is 3/8.
3x+8 = 5x+10 Take 3x away from both sides: 8 = 2x + 10 Take 10 away from both sides: -2 = 2x Divide both sides by 2: -1 = x

5/8
you have to take the square root of the number and add 5 so 9 -> 8
5+8 = 13
