Answer:

y = 3/8, x = 7/4

Step-by-step explanation:

x = 2y+1

-7(2y+1) - 2y = -13

-14y - 7 - 2y = -13

-16y - 7 = -13

-16y = -6

y = 3/8

Plug the value for y into one of the equations to solve for x

The area of a rectangular garden is 38 1/4 square meters the width of the garden is 4 1/2 meters what is the length of the garde
Snowcat [4.5K]

Hello...

Area is measured by the formula A=L*W (Area = Length X Width)  We know the area is 38 1/4 and the width is 4 1/2. It is easiest to convert them to decimals and solve. 38 1/4 = 38.25 and 4 1/2= 4.5 .    so, 38.25 = 4.5 * W

To solve for Width, we need to isolate it by getting 4.5 on the other side. To do this, we divide by 4.5 on both sides of the equals sign. this will give us W=8.5 or Width = 8 1/2 meters.
