Question

12x - y = -4 4x - 3y = -6 (1 point)

Answer 1

First step Substitute the value of y
4x-3(4+12x)= - 6
And this is your final answer

Answer 2

Answer:

Step-by-step explanation:

12x - y = -4  ----------------------(I)

4x - 3y = -6  ---------------------(II)

Multiply equation (I) by (-3)

(I)*(-3)                -36x + 3y = 12

(II)                       4x    - 3y = - 6  {Add and y will be eliminated}

                           - 32x     = 6

x = 6/-32

x = -3/16

Plugin the value of x in equation (I)

$12*\frac{-3}{16} -y=-4\\\\3*\frac{-3}{4}-y=-4\\\\\frac{-9}{4}-y = -4\\\\-y=-4+\frac{9}{4}\\\\-y=\frac{-4*4}{1*4}+\frac{9}{4}\\\\-y=\frac{-16}{4}+\frac{9}{4}\\\\-y=\frac{-7}{4}\\\\y=\frac{7}{4}\\\\y=1\frac{3}{4}$
