Answer:
x = 37
Step-by-step explanation:
Vertically opposite angles are equal
Therefore, 2x + 6 = 80
Subtract 6 from both sides: 2x = 74
Divide both sides by 2: x = 37
Answer:
add 33 to both sides
Step-by-step explanation:
Given
-
x - 33 = 33 ( add 33 to both sides )
-
x = 66 ( multiply both sides by - 2 to clear the fraction )
x = - 132
570-245 = 325
325 / 5 = 65

Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
This is the answer, attached below. :)
