First, we would simplify the numbers with exponents.
53-5 x 32(53=125, 52=9)
125-5 x 9
Next, we would multiply:
125-5 x 9 (5 x 9=45)
125-45
And then, subtract:
125-45 (125-45=80)
80
53-5 x 32=80
Factor out '5'
Hence 5(5^2 - 3^2)
Factor the brackets
5(5-3)(5+3)
5(2)(8)
5(16) = 80 THe answer.
-5
x + 5 = 3 x = -2
If: 3x = 5 then x = 5/3
x + 3 = 6xx - x + 3 = 6x - x3 = 5x3/5 = 5x/53/5 = x
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
2= x + 5 2 - 5 = -3 x= -3
Well, if x+3=5 and 2+3=5, I'm guessing x should equal 2
2
it equals 3.
x = -5/3
x = -5/3 y = -4/3
If you mean: x-5+5x = -3 then x = 1/3
