    2.32
    Commutative property
    associative property
    additive Identity Property
    additive Inverse Property

    7+ (8+y) = (8+y) + 7: Commutative property

    (8+a) + 5 = 8 + (a+5): associative property

    4+0=4: additive Identity Property

    Solve for u
    194 - u=292
    -u = 292 - 194
    -u = 98
    => u = -98

    Solve for x
    -5/7x=15
    Multiply each side by -7/5, we will get
    x = 15*(-7/5) = -21
    Answer: x = -21

    Solve for t
    2t + 11 = 51
    Subtract 11 from each side, we will get
    2t = 51 - 11
    2t = 40
    ⇨ t = 20
    Answer: t = 20

    Solve for w
    2w-8= -4
    add 8 to each side
    2w = 4
    ⇨ w = 4/2 = 2
    Answer: w = 2

    -13u -5 =8
    Add 5 to each side
    -13u = 13
    u = -1
    Find the value of u + 4 given that -13u -5 =8
    Simplify your answer as much as possible u+4= -1 + 4 = 3
