<span>2x+ y = 3
x = 2y - 1
Make sure there are NO SPACES in your answer. Include a comma in your answer.
It looks like I could substitute the x=2y-1. Into 2x+y=3
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1
x=1
(1,1)
CHECK
2x+y=3
2(1)+(1)=3
2+1=3
3=3
Left hand side=Right hand side
Check other equation
x=2y-1
1=2(1)-1
1=1
Therefore the solution is (1,1). Since the left hand side= right hand side in each equation</span>

Answer:
∠2 and ∠4 are the supplementary angle.
Step-by-step explanation:
Shelves of the bookcase are parallel and a transversal line is intersecting these points at two distinct points.
By the property,
Sum of two interior consecutive angles measure 180°.
From the figure attached,
∠2 and ∠4 are the interior consecutive angles.
Therefore, m∠2 + m∠4 = 180°
Which proves that shelves of the showcase are parallel.
