Answer:

Step-by-step explanation:

-5(4x + 3) = -5x - 5 - 15x - 10

-5*4x - 5*3 = -5x - 5 - 15x - 10

-20x - 15 = -5x - 5 - 15x - 10

-20x + 5x + 15x = -5 -10 - 15

0= 0

Answer:

Infinite Solutions

Step-by-step explanation:

Firstly we distribute

-20x - 15 = -5x - 5 - 15x - 10

Collect like terms

-20x - 15 = -20x - 15

This represents infinite solution because they will result in 0.

Consider the system of linear equations. x + y = 9.0 0.50 x + 0.20 y = 4.05 Find the values of x and y .

mixas84 [53]

Answer:

x=7.5

y=1.5

Step-by-step explanation:

$x + y = 9.0$

subtract x from both sides

$y=9-x$

$0.50x + 0.20y= 4.05$

$0.50 x +0.20(9-x)= 4.05$

$0.50x+1.8-0.2x= 4.05$

combine like terms

$0.30x+1.8= 4.05$

subtract 1.8 from both sides

$0.30x=2.25$

divide both sides by 0.3

x=7.5

$y=9-x$

$y=9-7.5$

y=1.5
