Hey there!

z * 0.4 = 0.4

0.4z = 0.4

DIVIDE 0.4 to BOTH SIDES

0.4z/0.4 = 0.4/0.4

CANCEL out: 0.4/0.4 (the LEFT side) because it gives you 1

KEEP: 0.4/0.4 (the RIGHT side) because it give you the z-value

NEW EQUATION: z = 0.4/0.4

SIMPLIFY IT!

z = 1

Good luck on your assignment and enjoy your day!
