12x - 28 = 18x - 88Put the variables on one side and the constants on the other by subtracting 12x from both sides and adding 88 to both sides.
12x - 12x - 28 + 88 = 18x - 12x - 88 + 88
Simplify
60 = 6x
Divide both sides by 6
x = 10
If you want to check your answer, which is always a good idea, plug in 10 for x in the original expression and see if you get a true statement:
12(10) - 28 = 18(10) - 88
120 - 28 = 180 - 88
92 = 92
If x equals 35, then -x equals -35.
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
x equals 8
Transitive property: If 8 equals x and x equals y, then 8 equals y.
Multiply width by length to get the area. The answer would be 336 square feet.

no.. x equals 11
x equals 14
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
If x=9, x=9
X +13 equals 22, X equals nine
x = ab x = 21*37 x = 777
