67 plus 3 equals 70.
5x - 9y = 43 (A)3x + 8y = 68 (B)(A)*3: 15x - 27y = 129(B)*5: 15x + 40y = 340Subtracting the first from the second gives67y = 211 => y = 211/67 = 3.15 approxSubstituting the [rational] value of y in (B)5x - 9*211/67 = 43 => 5x = 43 + 1899/67 = 4780/67therefore x = 956/67 = 14.27 approx.

17+67= 84
67 + 9 = 76
-25 + -42 = -67
the answer is 67
no it = 10

67 = x + 97-30 = x
Yes. This only works for multiplication and addition.
To calculate 67 tens plus 10 tens, you first convert the tens into their numerical values. This gives you 670 (from 67 tens) plus 100 (from 10 tens), which equals 770. Therefore, 67 tens plus 10 tens equals 770.
