Question

H + 5.4 = −5.4 pls help if you know

Answer 1

Answer:

$\sf H = -10.8$

________

$\sf Solve$

• $\sf Move~terms~not~containing~H~to~the~right.$

         $-5.4 + 5.4 = -10.8$

________

now, note that if this was actually subtracting, logically, the answer would be H = 0

however, this is an addition problem, meaning to add a negative and a positive integer to get a negative integer.

Answer 2

Multiply 5.4 x2 and put a negative symbol in front
