Tell whether the equation is true, false, or open.
83+(−12)=95
False
Tell whether the equation is true, false, or open.
10+4=14
True
Determine if the given value is a solution to the equation.
2x-3=9;x=6
To determine if x=6 is a solution to the equation 2x-3=9, we substitute x=6 into the equation and see if it holds true.
2(6) - 3 = 9
12 - 3 = 9
9 = 9
Since both sides of the equation are equal, x=6 is indeed a solution to the equation.
Determine if the given value is a solution to the equation.
2x-3=9;x=6
yes
or
no
Yes
Determine if the given value is a solution to the equation.
-9b+9=3;(1)/(3)
To determine if b=1/3 is a solution to the equation -9b+9=3, we substitute b=1/3 into the equation and see if it holds true.
-9(1/3) + 9 = 3
-3 + 9 = 3
6 = 3
Since both sides of the equation are not equal, b=1/3 is not a solution to the equation.
Determine if the given value is a solution to the equation.
-9b+9=3;(1)/(3)
yes
