Answer:
Step-by-step explanation:
first, let us mark the two equations as i and ii
2x+ 3y = 7
or, 2x = 7-3y
or, x = (7-3y) ÷ 2.........................(i)
and let 4x-5y= 25............(ii)
Now, put the the value of x from (i) into (ii)
4[(7-3y) / 2] -5y = 25
2(7-3y) -5y = 25
14- 6y - 5y = 25
-11y = 11
y = -1
Now, put y = -1 back in (i)
x = (7-3y)/2
x = 10 /2
x = 5
