x-5y
-4.28 -5(-4.68) =
-4.28 + 23.40 = +19.12
Now you round to the nearest tenth.
well 5 y = 23.4
so
x - 5 y = -4.28 - (-23.4)
minus a minus is a plus
so
x - 5 y = -4.28 + 23.4
= 19.12 which to the nearest tenth is 19.1
well 5 y = -23.4 forgot minus sign
so
x - 5 y = -4.28 - (-23.4)
minus a minus is a plus
so
x - 5 y = -4.28 + 23.4
= 19.12 which to the nearest tenth is 19.1
