Final answer:
Equation 1 has a solution of x = 23/19 and Equation 2 has a solution of x = -3.
Step-by-step explanation:
The given equations are:
Equation 1: 14x - 31 = -5x - 4
Equation 2: 12x + 31 + 8 = 3
To solve Equation 1, we can combine like terms:
19x - 27 = -4
Adding 27 to both sides:
19x = 23
Dividing both sides by 19:
x = 23/19
To solve Equation 2, we can combine like terms:
12x + 39 = 3
Subtracting 39 from both sides:
12x = -36
Dividing both sides by 12:
x = -3
Therefore, the solution to Equation 1 is x = 23/19 and the solution to Equation 2 is x = -3.
