Answer 1

Answer:

Solve equation [2] for the variable x

[2] 2x = 5y + 15

[2] x = 5y/2 + 15/2

// Plug this in for variable x in equation [1]

[1] 3•(5y/2+15/2) + 5y = 10

[1] 25y/2 = -25/2

[1] 25y = -25

// Solve equation [1] for the variable y

[1] 25y = - 25

[1] y = - 1

// By now we know this much :

x = 5y/2+15/2

y = -1

// Use the y value to solve for x

x = (5/2)(-1)+15/2 = 5

Answer 2

Answer:

$\frac{30(2x-5y)}{x}$

Step-by-step explanation:

$=10\left(2x+5y\right)\frac{3}{x}$

=$\frac{3X10(2x+5y)}{x}$

=$\frac{30\left(2x+5y\right)}{x}$
