Answer:

w=3 h=4

Step-by-step explanation:

14=2w+2h      w=(3/4)h

substitute

14=2(3/4)h+2h

distribute

14=1.5h+2h

simplify

14=3.5h

divide both sides by 3.5

4=h

plug into original equation

w=(3/4)4

w=3

Zielflug [23.3K]

Answer:

Therefore the Final Solution is

x = 1 and y = 1

Step-by-step explanation:

Given:

x=y                ...............Equation ( 1 )

x+2y=3         ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Equating Equation  ( 1 ) in Equation ( 2 ) we get

y+2y=3\\\\3y=3\\\\y=\frac{3}{3} \\\\\therefore y =1

Now Substituting y = 1 in Equation ( 1 ) we get

x =1\\\\\therefore x=1

Therefore the Final Solution is

x = 1 and y = 1
