6 0

Answer:

2x - 6 = 4

Step-by-step explanation:

Firstly, let's assume the number is x

Then, twice the number is 2 times x = 2x

6 less than twice the number is four

2x - 6 = 4

2x - 6 + 6 = 4 + 6

2x = 10

2x/2 = 10/2

x = 5

3/2y-3+5/3 when y=6 and z=3
marissa [1.9K]

Answer:

5 \frac{1}{3}

Step-by-step explanation:

Assuming We want to evaluate

\frac{3}{2y - 3} +  \frac{5}{3} z

When y=6 and z=3.

We substitute to get:

\frac{3}{2 \times 6 - 3} +  \frac{5}{3}  \times 3

We multiply to get:

\frac{3}{12 - 3} +  \frac{15}{3}

We simplify the denominator to get:

\frac{3}{9} +  \frac{15}{3}

Reduce the first fraction:

\frac{1}{3} +  \frac{15}{3}

Add the numerator and keep one denominator for they are like fractions

\frac{16}{3}

Write as a mixed number:

5 \frac{1}{3}
