9x+3y=6
solving by substitution

Answer 1

I hope that help to solve the sum

Answer 2

Step-by-step explanation:

$9x + 3y = 6\\ put \: \: \: \: y = - 3x + 2 \\ \\ 9x + ( - 3x + 2) = 6 \\ 9x - 3x + 2 = 6 \\ 9x - 3x = 6 - 2 \\ 6x = 4 \\ x = 4 \div 6 \\ x = 2 \ \div 3$

x = 2÷3

y = -3x+2

= -3(2÷3)+2

= -2+2

= 0
