x+5y=9 and 3x+2y=14 solve using substitution method
Answers
Answer:
x=9-5y equation1
3x+2y=14 equation 2
now put the value of x in equation 1 we get
3(9-5y)+2y=14
27-15y+2y=14
27-13y=14
-13y=14-27
-13y=-16
y=16/13
y=1.23
now put the value of y in equation 1
x=9-5y
x=9-5*1.23
x=9-6.15
x=2.85
i hope this will help u
Step-by-step explanation:
Answer:
x = 5 & y = 1
Step-by-step explanation:
GIVEN:
x + 5y = 9 ....(i)
3x + 2y = 14 ....(ii)
TO FIND:
Using Substitution method,
x = ?
y = ?
SOLUTION:
By eq.(i),
x + 5y = 9
x = 9 - 5y ....(iii)
Putting value of x in eq.(ii),
3x + 2y = 14
=> 3(9 - 5y) + 2y = 14
=> 27 - 15y + 2y = 14
=> -13y = 14 - 27
=> -13y = - 13
=> y = -13/-13
y = 1
Now,
Putting y = 1 in eq. (iii)
x = 9 - 5y
= 9 - 5×1
= 9 - 4
= 5
Therefore, x = 5 & y = 1
