Just substitute in the number 3 for x then subtract 3 at both sides and youll have y=7
The two-digit number you are looking for is 12.
4 x 3 = 12.
6 x 2 = 12.
This fits your criteria.
2x + 3y = -6 (Subtract 2x from both sides)
3y = -2x - 6 (Divide both sides by 3 to isolate x) which will give you y = -2/3x - 2 and this graphed would cross the x-axis at (-3,0) and the y-axis at (0, -2). So a + b = -5
2/3
16/24 and divide the greatest common factor (8)
So to find the mean you add them all together and divide by the number of numbers there is so 11+15+19+17+23+20+17+18+21=174 and there are 10 numbers so it would be 174/10 which is 17.4 so you answer is 17.4
