Solve each of the following systems, if possible. indicate whether the system has a unique solution, infinitely many solutions, or no solution. a. 2x + 10y = 9
3x + 15y = 13

b. 2x + 8y = 5
3x + 12y = 7.5

c. y = 3-x

d. 5x -8y = -1
-5/2 x + 4y = 1/2​

(a) No solution

(b) Infinitely many solution

(c) No solution

(d) Infinitely many solution

Step-by-step explanation:

Solving (a):

--- (1)

--- (2)

Multiply (1) by 1.5

1.5 * []

--- (3)

Subtract 2 and 3

The above is false; Hence, the system has no solution

Solving (b):

--- (1)

-- (2)

Multiply 1 by 1.5

1.5 * []

Subtract 2 and 3

The above implies that the system has infinitely many solutions

Solving (c):

A second equation is required to solve for (c)

Solving (d):

--- (1)

--- (2)

Multiply (2) by 2

--- (3)

Add 1 and 3

The above implies that the system has infinitely many solutions

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
