-2x + y = 0<br> x - y = -3

miv72 [106K]

Answer:

The value of x is 3 and y is 6.

Step-by-step explanation:

You can solve this simultaneous equation by elimination method :

$- 2x + y = 0 - - - (1)$

$x - y = - 3 - - - (2)$

$(1) + (2)$

$- 2x + y + x + (- y) = 0 + ( - 3)$

$- x = - 3$

$x = 3$

$substitute \: x = 3 \: into \: (2)$

$(2)⇒$

$3 - y = - 3$

$- y = - 6$

$y = 6$

It takes Ralph 12 hours to paint a fence alone. Lisa can do the same job in 15 hours. If Ralph paints alone for 40 minutes befor

Aleks [24]

After 40 minutes, Ralph has already painted (40/60)/12=1/18 of the fence

Lisa's speed is 1/15 fence/hour, Ralph's speed is 1/12 fence/hour, hence when they help each other their combined speed is 1/15+1/12=3/20

Thus we need to solve 3/20*x=17/18 thus x=170/27 hours (approx 6 hours 15 mins)
