Term
 x+3=-10
Definition
 x+3=-10   -3    -3          Additive Inverse Property     x=-13 x+3=-10       Rewrite original equation -13+3=-10    Plug in answer to check -10=10         Both sides are the same
Term
 4x-5=19
Definition
 4x-5=19    +5  +5  Add 5 to both sides to cancel out subtract 5 4x=24 /4   /4      Divide 4 on both sides to cancel multiply 4 x=6   4x-5=19    Rewrite original equation 4(6)-5=19 Plug in your answer to check for validity 24-5=19    Simplify both sides using PEMDAS 19=19      Answer is the same on both sides!
Term
 9r + 15 = 87
Definition
 9r + 15 = 87      -15    -15  Subtract 15 to cancel +15 9r=72             /9  /9            Divide 9 both sides to cancel multiply 9 r=8 9r+15=87      Rewrite original equation 9(8)+15=87   Plug in answer to check 72+15=87      Simplify using PEMDAS 87=87           Both sides are equal
Term
 b/13+12=19
Definition
 b/13+12=19        -12   -12   Subtract 12 to cancel out +12 b/13=7 *13    *13         Multiply by 13 to cancel out divide 13 b=91 b/13+12=19    Rewrite original equation 91/13+12=19   Plug in answer to check 7+12=19          Simplify using PEMDAS 19=19              Both sides are true
Term
 3-7m = 18
Definition
 3-7m = 24 -3         -3     Subtract 3 to cancel out the positive 3 -7m=21 ÷(-7) ÷(-7)   Divide by negative 7 to cancel out  m=-3 3-7m=24       Rewrite original equation 3-7(-3)=24     Plug in answer to check 3+21=24       Simplify using PEMDAS 24=24          Both sides are equal
