If: x+y = 8 and 2x-y = 5 Then by adding the equations together: 3x = 13 or x = 13/3 By substitution into the original equations: x = 13/3 and y = 11/3
Yes that is correct
2x+3y=13 3x-y=3 x=2
13 to the 6th power equals 4,826,809

It is 11*13 = 143
13 + 130 = 143
-13 + 24 = 11
143/11 = 13
13 - 2 = 11
X + 11 = 13.Subtract 11 from both sidesX + 11 - 11 = 13 - 11X = 2
-11
b-11 = -13 add 11 to BOTH sides b = -2
nope. It equals five. Think of it as positive 13 minus 8.
3j-13=11+2j 3j-13-2j = 11+2j-2 j-13 = 11 j-13 +13 = 11 + 13 = 24 so j = 24
13 multiplied by 11 is 143.
