Answer:
The value of your expression is 7/12x +1.
Step-by-step explanation:
  1/4x + 3 - 1/3x + -2              First, positive and negative is negative
= 1/4x + 3 - 1/3x -2                 Combine like terms, 1/4x and 1/3x
= 7/12x + 3 - 2                          Combine like terms, +3 and -2
= 7/12x +1
Like terms are when a number have similar exponents bases, variables or just plain numbers.
3x, 4x, 5x
1.02x^2, 1.02x^3

Answer:
81 sodas and 50 hotdogs
Step-by-step explanation:
131 = x + x - 31
131 <em>+</em><em> </em><em>3</em><em>1</em><em> </em>= x + x - 31 <em>+</em><em> </em><em>3</em><em>1</em>
162 = x + x
x = 81
131 = 81 + (81 - 31)
131 = 81 sodas + 50 hot dogs
