2x+3y=4 4x+6y=9 what is the value of x and y

No Solution.

Step-by-step explanation:

2x+3y=4

4x+6y=9

-2(2x+3y)=-2(4)

4x+6y=9

-4x-6y=-8

4x+6y=9

0=1

no solution

No solution.

Step-by-step explanation:

2x + 3y = 4

4x + 6y = 9

Multiply both sides of the first equation by -2. Then write the second equation below it and add them.

       -4x - 6y = -8

+       4x + 6y = 9

           0 + 0 = 1

Since the statement 0 = 1 is false, there is no solution to this system of equation.

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
