Find the solution of the system of linear inequalities.

1.4x + 7y = 21
10x - 2y = 16

y ≥ 2.576923

Step-by-step explanation:

1.4x + 7y ≥ 21 simplify, you must

0.2x + y ≥ 3 isolate in terms of "y", it would be wise to do

y ≥ -0.2x + 3

10x - 2y ≥ 16 simplify, you should

5x - y ≥ 8 isolate in terms of "y", it is best to do

(1) y ≥ -0.2x + 3

(2) -y ≥ 8 - 5x add inequality (1) and inequality (2) together

0 ≥ -5.2x + 11 isolate "x", sense it will make

-11 / -5.2 ≥ x simplify for "x"

2.115385 ≥ x

y ≥ -0.2(2.115385) + 3 solve for value of "y"

y ≥ 2.576923

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
