Answer:

\boxed{\bold{One \ Solution}}

Step-by-step explanation:

  • <u>Solve equation to find answer(s)</u>

<u></u>

Combine: 6z - 3z = 3z

\bold{3z-7=-2+3}

Add: -2 + 3 = 1

\bold{3z-7=1}

Add 7 to both sides:

\bold{3z-7+7=1+7}

Simplify:

\bold{3z=8}

Divide both sides by 3:

\bold{\frac{3z}{3}=\frac{8}{3}}

Simplify:

\bold{z=\frac{8}{3}}

Needed help for my math please
vesna_86 [32]

Answer:

see explanation

Step-by-step explanation:

(a)

\frac{a}{a} = 1 ( any value divided by itself = 1 )

(b)

\frac{a}{1} = a ( any value divide by 1 is the value itself )

(c)

\frac{a}{b} × \frac{c}{d} = \frac{ac}{bd}

The product of 2 fractions is the product of the numerators divided by the product of the denominators

(d)

\frac{a}{b} ÷ \frac{c}{d} = \frac{ad}{bc}

To divide 2 fractions, leave the first fraction, change division to multiplication and turn the second fraction upside down, that is

\frac{a}{b} ÷ \frac{c}{d} = \frac{a}{b} × \frac{d}{c} = \frac{ad}{bc}

(e)

\frac{a}{d} + \frac{b}{d} = \frac{a+b}{d}

Since the fractions have a like denominator, add the numerators leaving the denominator. This applies to subtraction also

(f)

\frac{a}{d} - \frac{b}{d} = \frac{a-b}{d}

See explanation for part (e)
