What is the best method to solve the below system of equations
3x + 2y =5
y=2x+3

ANSWER 1

Consider the given equation,

3x−2y=5

put x=0 then,

3×0−2y=5

y=−25

Now, put y=0 then,

3x−2×0=5

x=35

Hence, (0,−25)  and  (35,0) is the answer.

ANSWER

As can be seen, the line for y=2x+3 extends up to infinity all over the number line.

For x=0,y=3, For x=1,y=5, For x=2,y=7 

∴ For every value of x we get the different value of y   

Hence it will have infinitely many solutions.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
