Question

Solve this equation by substitution method..
2x+3y=5; 3x-9=4y ​

Answer 1

Step-by-step explanation:

2x + 3y is = 5 that is first equation

3x-9 is = 4 that is second equation

from first equation:

x = (5-3 y) / 2 ........(3)

substituting x in second equation:

3( 5 - 3y)/ 2 =4 y

15 - 9 y = 8 y

15= 8 y + 9 y

15=17y

y=15/17

substituting y in (3) equation:

x=(5-3(15/17))/2

x=30/34
