False because it does not have an equality sign and so therefore it is not an equation.
False because without an equality sign the given expression can't be considered to be an equation.
-4
(2, 3) is a solution only if it satisfies the equation. x + 5y = 4 (2) + 5(3) =? 4 2 + 15 =? 4 17 = 4 False Therefore, (2, 3) is not a solution to the given equation.
True
For a value to be a solution to an equation, when you substitute the value for the variable, the equation becomes true. 4+B=6 B is the variable. 2 is the solution Substitute 2 for B 4+2=6 The equation is true.
-1
6
False because without an equality sign the given expression can't be considered to be an equation.
An equation is a true statement. [ 75 + 4 = -2 ] is a false statement.
-4
False because it is 3/4
11
true
To determine if (4, -3) is a solution to the system, we need to substitute x = 4 and y = -3 into both equations. For the first equation (3x - 3y = 21): (3(4) - 3(-3) = 12 + 9 = 21) (True) For the second equation (5x + 4y = 24): (5(4) + 4(-3) = 20 - 12 = 8) (False) Since (4, -3) does not satisfy the second equation, it is not a solution to the system.
True
-4
No. [ 4+3=9 ] is just a plain old false statement.
