Answer:
x = 12
Step-by-step explanation:
This equation is very easy to solve.
3x - 13 = 23 Add 13 to both sides of the equation.
3x = 36 Divide by 3 on both sides of the equation.
x = 12
Then, check your answer by substituting the solved value.
3(12) - 13 = 23
36 - 13 = 23
23 = 23
Therefore, x = 12 is the solution to the equation.

Answer:
-1 , -6
Step-by-step explanation:
Let x be the first number and let y be the second number.
x * y = 6
x + y = -7
Let's first find the factor pairs of 6.
1, 6
2, 3
-1, -6
-2, -3
Now, we just need to take each factor pair and add them together and see which one equals -7.
1 + 6 = 7, so that is wrong.
2 + 3 - 5, so that is also wrong.
-1 - 6 = -7, so this is our answer (-2 and -3 added is -5, which is wrong).
Therefore, our answer is -6 and -1.
