Question

simplify:-
x+y = 15 and 2x+3y = 37
a.) x = 7 and y = 8
b.) x = 8 and y = 7
c.) x = -8 and y = -7
d.) x = -7 and y = -8​

Answer 1

Answer:

• x+y=15
• x=15-y

Now,Put the value in 2nd equation.

• 2x+3y=37
• 2(15-y)+3y=37
• 30-2y+3y=37
• y=37-30
• y=7

And,x=15-y

• x=15-7
• x=8.

Answer 2

Step-by-step explanation:

x+y=15-------1

x+y=15-------12x+3y=37------2

by substitution method:-

x+y=15

x=15-y-----3

Put the value of x in equation 2

2(15-y)+3y=37

30-2y+3y=37

y=37-30

y=7

Put this value of y in equation 3

x=15-y

= 15-7

x =8

Hence x=8 and y=7

Thus ur answer is option (b)
