First, you have to send 5x to the other side so youĺl -5x and the equation will be -6y>-5x+42
Then, you divide the equation on the left side by -6 because youll want y by itself. Remember, when you divide by a negative, you flip the greater than/equal to sign. itll now be y<-5/6 - 7
A) x + y = 7 B) 10y + x = 10x + y + 9 collecting terms of equation B B) -9x + 9y = 9 multiplying A) by 9 A) 9x + 9y = 63 then adding it to equation B) B) -9x + 9y = 9 18y = 72 y = 4 x = 3
