42 degrees. Divide 105 by 5 and get 21 and then multiply it by 2.
Answer:
x=-2
Step-by-step explanation:
divide each term by 50, then simplify.(4x+12=4)
Move all terms not containing x to the right side of the equation.(4x=-8)
divide each term by 4 then simplify. (x=-2)
-4, -1, -0.2, 7/10, root of 2, 2
Perhaps you can try plugging your value of x in and showing that x+25=40. That is probably what your teacher wants to see
