    z=2.58

    Step-by-step explanation:

    1.918=9.4-z (2.9)

    Simplify both sides of the equation.

    1.918=-2.9z+9.4

    Flip the equation.

    -2.9z+9.4=1.918

    Subtract 9.4 from both sides.

    -2.9z+9.4-9.4=1.918-9.4

    -2.9z=-7.482

    Step 4: Divide both sides by - 2.9.

    -2.9z/-2.9 = - 7.482/-2.9

    z=2.58

    Answer:

    z=2.58
