-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
6 and -4, because a neg. times a pos. equals a neg. (in this case 6*(-4)= -24) and when adding and subtracting integers you subtract the smaller number from the larger number, in the case 6 and 4, which is 2
9 + 9 + 9 + 9 + 9 + 9 + 6 + 6 + 6 + 6 + 2 + 2 + 23 + 3 + 3 + 4 + 4 + 4 = 123
3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 = 49.6
a negative
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
x=3 and y=4. you multiply x+y=7 by neg. 2 this way you can cancel out the y factors and get neg. 2x+x=-14+11 neg. x = neg. 3 divide both sides by neg. 1 to get x=3. use substitution to get y=4
neg(-k) + neg(-k) = k + k = 2k = 4
6 and -4, because a neg. times a pos. equals a neg. (in this case 6*(-4)= -24) and when adding and subtracting integers you subtract the smaller number from the larger number, in the case 6 and 4, which is 2
6 + 4 + 3 + 4 + 4 + 5 + 4 + 6 + 5 + 4 + 8 + 4 = 57
4 + 6 + 6 + 5 + 5 + 4 + 6 + 5 + 5 + 6 + 5 + 5 + 5 + 3 = 70
9 + 9 + 9 + 9 + 9 + 9 + 6 + 6 + 6 + 6 + 2 + 2 + 23 + 3 + 3 + 4 + 4 + 4 = 123
7 + 5 + 4 + 5 + 3 + 4 + 6 + 5 + 4 + 5 + 6 + 4 + 7 = 65
3+4+6+4=17
6 + 4 = 4 + 6 is an example of the Commutative property of addition.
3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 = 49.6
