Answer:
x = 4
y = 2
Step-by-step explanation:
by using substitution method ;
now, in second equation ;
- 2x + 3y = 14
- 2 (8 - 2y) + 3y = 14
( since x = 8-2y, from equation 1 )
- 16 - 4y + 3y = 14
- 16 - y = 14
- -y = 14 - 16
- -y = -2
- y = 2
<em>i</em><em> </em><em>hope</em><em> </em><em>it</em><em> </em><em>helped</em><em>.</em><em>.</em><em>.</em>
putting value of y in equation 1, we get :
- x + 2y = 8
- x + (2 × 2) = 8
- x + 4 = 8
- x = 8 - 4
- x = 4
Answer:
Width = 5 inches
Length = 9 inches
Step-by-step explanation:
The paper;
Length = (x + 4) inches
Width = x inches
The area is close as possible to 50 square inches.
Since this paper is rectangular in shape; the area of a rectangle is given by:
Area = Length × Width
∴ (x + 4) * x = 50 square inches
x² + 4x = 50
Let the area be equal to 45 square inches;
Applying the quadratic formula, x = 5 or -9
But since we are dealing with length measurements, the value of x = 5 inches.
So the width = 5 inches and;
length = 5 + 4 = 9 inches.
