Solve each system of equation by substitution y=-x+5 x+2y=2

Likurg_2 [28]

Answer:

$x = 8$

$y = -3$

Step-by-step explanation:

Given :

$y = -x + 5$ ...................... equation 1

$x + 2y = 2$ ........................ equation 2

solving the system of linear equation by substitution method , substitute equation 1 into equation 2 , that is

$x + 2(-x+5) = 2$

$x - 2x + 10 = 2$

$-x + 10 = 2$

collect the like terms

$10 - 2 = x$

therefore :

$x = 8$

substitute $x = 8$ into equation 1 to find the value of y , that is

$y = -8 + 5$

$y = -3$

Therefore :

$x = 8$

$y = -3$

hamburgers cost $2 per lbs and chicken costs $3 lbs and you only have $30 to spend and expect At least 3lbs of hamburger

kicyunya [14]

If you want at least 3 pounds of hamburgers, then $6 is enough to buy those 3 pounds of hamburgers. If you ONLY buy 3 Pounds, then you also have enough for 4 pounds of chicken. $3 a pound x 4 = $12. You have 2 dollars left to spare, which means you can buy another pound of hamburgers. So 4 pounds each are able to be purchased.
