Answer:
A) 6x + 5y = 82
B) 2x + 5y = 54 We'll multiply equation B) by -1
B) -2x -5y = -54 Then we'll add this to A)
A) 6x + 5y = 82
4x = 28
x = 7
y = 8

Answer:
x = 4
Step-by-step explanation:
Answer:
2x + 3y ≥ 5
Step-by-step explanation:
See the graph attached.
The bold straight line passes through the points (1,1) and (4,-1).
Therefore, the equation of the straight line will be
⇒ 3(y + 1) = - 2(x - 4)
⇒ 3y + 3 = - 2x + 8
⇒ 2x + 3y = 5 ............. (1)
Now, the shaded region i.e. the solution to the inequality does not include the origin(0,0).
So, putting x = 0 and y = 0 in the equation (1) we get, 0 < 5
Therefore, the inequality equation is 2x + 3y ≥ 5 (Answer)
