Question

Please help me its about solving system by substitution

Answer 1

x = 2 and y = 5

Explanation:

Given

x = y - 3.....i)

2x + 3y = 19.........ii)

Putting x = y - 3 in equation II)

2( y - 3 ) + 3y = 19

2y - 6 + 3y = 19

5y = 19 + 6

5y = 25

y = 25 / 5

y = 5

Now putting y = 5 in equation i)

x = 5 - 3

x = 2

Hope it will help :)❤
