Plz 20 ! i will give ! solve the system of linear equations below. y = -2x + 19 y = x + 7 a. x = 4, y = 11 b. x = -12, y = -5 c. x = -4, y = 3 d. x = 8, y = 3

A

Step-by-step explanation:

since both equations express y in terms of x we can equate the right sides

x + 7 = - 2x + 19 ( add 2x to both sides )

3x + 7 = 19 ( subtract 7 from both sides )

3x = 12 ( divide both sides by 3 )

x = 4

substitute x = 4 into either of the 2 equations for y

y = x + 7 ⇒ y = 4 + 7 = 11

solution is (4, 11 )

gdp is the best phrase!

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
