Mathematics
1 answer:
WITCHER [35]3 years ago
3 0

Answer:

c.) x = 3

Step-by-step explanation:

2x - 3y = 9

x = 4 + y

Substitute the second equation into the first equation

2(4+y) - 3y = 9

Distribute

8+2y -3y =9

8-y = 9

Subtract 8 from each side

8-y-8 =9-8

-y = 1

Multiply by -1

y =-1

Now solve for x

x = 4-1

x =3

Answer:

\sf \dfrac{3}{4y}

Step-by-step explanation:

Simplify:

  45 = 5 * 3 * 3

  60 = 5 * 3 * 2 * 2

GCF = 5*3 = 15

           \sf \dfrac{45x^2}{60x^2y}=\dfrac{45}{60y}

                     \sf =\dfrac{45 \div 15}{60y \div 15}\\\\= \dfrac{3}{4y}
