Question

find the solution of the following system of equation by substitution method ?
4x + 9y = 5
3x - 5y = 39 how to slove

Answer 1

HEY MATE !!!!!
HERE IS UR ANSWER ⬇️⬇️
___________________________________
4x +9y = 5-------->(i)
3x - 5y = 39 --------->(ii)

===============
USING SUBSTITUTION METHOD :

From equation (i)
4x +9y = 5
4x = 5-9y
x = 5 - 9y/4--------> (iii)

Putting the value of x in equation (ii)
3x-5y =39
3(5-9y/4)-5y = 39
15 - 27y - 20y = 156
-47 y = 156 - 15
-47y = 141
y = -3

===============
PUTTING THE VALUE OF y in equation (iii)
x = 5-9y/4
x = 5 +27/4
x = 32 /4
x = 8

So, x = 8 and y = -3
