12
If you were using base 4 then a single digit number could have 4 possible values:
0,1,2 & 3. To represent the next number (4) we would have to introduce a second digit to the left of the first (i.e. a 1) and reset the first digit back to 0 again (i.e. 10). Then 5 would be 11 and 6 would be 12.
Another way to look at it is that in base 4 the number 12 means:
(2 * 40) + (1 * 41) = 2 + 4 = 6.
10
To solve this question you need to divide 24 by 4 and using basic multiplication and division the answer to the question is 6.
(2,-2)
6 base 4 = 12 Check Related links
That factors to 2(x + 4)(x + 6) x = -4, -6
2x3-10 is -4, as (using BIDMAS), we firstly multiply 2 by 3 (6) and finally subtract the 10, leaving us with -4.

2x-y = 4 and 2y = 4x-6 pick either equation and solve for one of the variables the first equation: y = -4 + 2x plug in the value of variable you solved for into the other equation 2(-4 + 2x) = 4x -6 then solve -8 + 2x = 4x-6 -2 = 2x x= -1 then plug in the value you have found into either original equation to find the value of the other variable 2(-1) - y = 4 -2 - y = 4 -y = 6 y = -6
