20 - 4 - 2 = 14. A negative number is just like subtracting it.
The fraction equivalent is 1/3 = 2/6 because when u simplify 2/6 =1/3
The First two coefficients are positive because they are on the positive side of the y-axis.
The Last two are on the negative side of the y-axis. B is the closest to zero as the wider the graph is, the lower the coefficient is.
The coefficient with the greatest value would be D
To find x just change the <span>> to a =
</span><span>3x-7=5
add 7
3x=12
then divide by 3
x=4
