Z- 6.3 = 2.1
Solve the equation

Z = 8.4

Step-by-step explanation:

Jusg move 6.3 behind

When something negative moves behind it becomes positive

So 2.1 plus 6.3 is 8.4

Z=8.4

Step-by-step explanation:

1. Add 6.3 to both sides.

Z =2.1+6.3

2.Simplify 2.1+6.3 to  8.4

Z=8.4

(Checking answer)

Z−6.3=2.1

1. Let Z=8.4

8.4-6.3=2.1

2. Simplify  8.4-6.3 to  2.1

2.1=2.1
