Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
10x + 5 which is also equal to 5(2x + 1)
x=(-9/7) 7x+12=3 7x=(-9) x=(-9/7)
7x-2
hujkImproved anwser:2x+6 = 7x-42x-7x = -4-6-5x = -10x = 2
-46 = 3x + 7x
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
abc = 38
From C2H5.OH: One and two sevenths
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
