Answer:

[tex] \frac{3(2) + 7}{2(2) - 3} \\ = \frac{6 + 7}{4 - 3} \\ = \frac{1}{1} or1[/tex]

[tex]2(4) + 15 \\ = 8 + 15 \\ = 23[/tex]

[tex]3(2)(3) + 7 - (4) \\ = 3(6) + 7 - 4 \\ = 18 + 7 - 4 \\ = 21[/tex]

Step-by-step explanation:

pa-follow. thanks

[tex] \frac{13}{2} x - y[/tex]

Solution:

[tex]3x + 7 \div 2 \times x - y[/tex]

[tex]3 \times + \frac{7}{2} x - y[/tex]

[tex] \frac{13}{2} x - y[/tex]

The expression is not factorable with rational numbers.

[tex]2z + 15[/tex]

Simplify the expression.

[tex]3xy - z + 7[/tex]
