Pls i need these to be finished by tomorrow, i'll give brainliest to whoever the best. 1st. (try the numbers 31, 32, 33, 34 in the equation 4 × (x + 8) = 5x − 2 to test whether any of them is a solution. a. 31 is a solution. c. 33 is a solution. b. 34 is a solution. d. 32 is a solution.)

2nd. (try the numbers 9, 10, 11, 12 in the equation 60 − 3 ⋅ z = 30

to test whether any of them is a solution.

a. 11 is a solution. c. 12 is a solution.

b. 10 is a solution. d. 9 is a solution.)

Part a: Option b. 34 is a solution.

Part b: Option b. 10 is a solution.

Explanation:

Part a: The equation is

To find solution to the equation, we can solve for x.

The solution is

To test whether is a solution, let us substitute in the equation , we get,

Since, the values on both sides of the equation are equal, is the solution.

Part b: The equation is

To find solution to the equation, we can solve for z.

The solution is

To test whether is a solution, let us substitute in the equation , we get,

Since, the values on both sides of the equation are equal, is the solution.

yor answer is 7/6 times 5
