(7x)-6=-12 7 times a number is 7x or 7 times any variable. Six less than that is subtracting by 6 then it all equals -12
<span>
</span>Calculate 3 x 5, which is 15.Since 15 is two-digit, we carry the first digit 1 to the next column.
Calculate 5 x 5, which is 25. Now add the carry digit of 1, which is 26.Since 26 is two-digit, we carry the first digit 2 to the next column.
Bring down the carry digit of 2.
<span>Therefore, 53 x 5 = 265.</span>
Multiply the numbers on the major axis which are 2 and -9 to get -18. Subtract from that 3*4 = 12. So -18-12 = -30. That's the determinant.
