6x+y=-9 , 2x -3y=-5
Answers
Answer:
x=-1.6 and y=0.6
Step-by-step explanation:
2(6x +y=-9)
6(2x-3y=-5)(we take the coefficient of 6x ie 6 and multiply it by 2x-3y=-5 and we do the same to the coefficient of 2x but with the coefficient of 2x ie 2 is multiplied by 6x +y=-9)
after multiplying you get :
12x +2y=-18
12x -18y=-30(we cancel both 12 x)(then we minus 2y- -18y and -18--30)
you get 20y=12(divide both sides by 20 and simplify)
after simplifying you get the value of y ie 0.6
so u use the value of y to get the value of x ie
6x +0.6(ie the value of y we substituted y and used 0.6 instead)=-9
(take 0.6 to the other side becomes -0.6 -9)
6x=-9.6(after adding -0.6 and -9)(then divide both sides by 6 and simplify
after simplifying you will get the value of x as -1.6
