-1.6x - 3.2y=-24
2.6x + 2.6y = 26
The solution is (

Answers

Answer 1

Answer:

Answer:

$x=5\ny=5$

Step-by-step explanation:

I solved using substitution

−1.6x−3.2y=−24

−1.6x=−24+3.2y

−1.6x=3.2y−24

$x=-(3.2y-24)/(1.6\n)$

2.6x+2.6y=26

−2.6y+39=26

−2.6y=26−39

−2.6y=−13

y =5

D. has slope of 6

Therefore, C. has the highest slope.

Find the solution set for the system of equations.
9x + 5y = 28
5x + 9y = 56

Answers

9x + 5y = 28 . . . . . (1)
5x + 9y = 56 . . . . . (2)

(1) x 5 => 45x + 25y = 140 . . . . . (3)
(2) x 9 => 45x + 81y = 504 . . . . . (4)

(3) - (4) => --56y = -364 => y = 6.5

From (1), 9x + 5(6.5) = 28 => 9x = 28 - 32.5 = -4.5 => x = -4.5/9 = -0.5
