-2 is a solution of the equation 4 - 2x = 8.
Q 3. Solve the following equation: m - 8 = 14(1 point) Responses m = 6 m = 6 m = 20 m = 20 m = 12 m = 12 m = 22
m = 22
Q 4. Which ordered pair is a solution of y = x - 5?(1 point) Responses (7, 2) (7, 2) (11, 4) (11, 4) (2, 7) (2, 7) (2, 3)
(7, 2) is a solution of y = x - 5.
Q. 5. Solve the following equation: 10 + x3=110 + x3=1 (1 point) Responses x = - 7 x = - 7 x = 33 x = 33 x = -27 x = -27 x = 21
The equation 10 + x^3 = 1 has no solution.
The equation 3x + 1 = 22 is an equation with a variable, so we need to determine if it is true, false, or open.
To do this, we can solve the equation by isolating the variable. Begin by subtracting 1 from both sides of the equation:
3x + 1 - 1 = 22 - 1
This simplifies to:
3x = 21
Now, divide both sides of the equation by 3 to solve for x:
(3x) / 3 = 21 / 3
x = 7
Since we have found a value for the variable x that makes the equation true, the equation 3x + 1 = 22 is true. Therefore, the correct response is True; the expressions are the same for all values of the variable.
