Question

2x+3y=3 4x+4y=4 solve by subsitiution method​

Answer 1

Answer:

x = 0

y = 1

Step by step solution:

2x + 3y = 3

2x = 3 - 3y

x = 3 - 3y / 2

4x + 4y = 4

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

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

6 - 6y + 4y = 4

-6y + 4y = 4 - 6

-2y = -2

y = -2/-2

•°• y = 1

x = 3 - 3y/2

= 3 - 3/ 2

= 0/2

= 0
