-15 = m
Step-by-step explanation:
-16 = -1 + m
-16 + 1 = m
-15 = m
Why does -1 became +1 , It is because you are adding 1 on both side so that we can cancel out the -1 and it will rest the m.
like this;
+1 -16 = -1 + m +1
-16 + 1 = (0 or nothing) + m
-15 = m

The perimeter of a rectangle is 62m. find the length of its sides if it is known that the area of the rectangle is 1980000 cm².
Step - by - step equation:
4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x = 18x + 6 + 8
20x = 18x + 14
20x - 18x = 14
2x = 14
x = 14 / 2
x = 7
