There is one solution in the system of equation
<h3>How to determine the number of solutions?</h3>
The system of equations is given as:
8x=12y-9 and 27y+18x=21
Divide 8x=12y-9 by 8
x = 1/8(12y-9)
Substitute x=1/8(12y-9) in 27y+18x=21
27y + 18 * 1/8(12y-9) =21
Expand
27y + 27y - 20.25 =21
Evaluate the like terms
54y = 41.25
Divide by 54
y = 0.7639
Hence, there is one solution in the system of equation

Answer:
x = 32°
Step-by-step explanation:
The consecutive angles in a parallelogram are supplementary.
∠ A and ∠ D are consecutive angles, then
131 + 17 + x = 180
148 + x = 180 ( subtract 148 from both sides )
x = 32°
