Please solve these 2 ;-;<br><br> y = 2x – 6<br> y = –4x + 3
Yuri [45]

Answer:

x = 3/2 | y = -3

Step-by-step explanation:

Given equations:

  • y = 2x - 6. . . .(i)
  • y = -4x + 3. . . . (ii)

Substituting from equation (i) for y:

==> 2x - 6 = -4x + 3

==> 2x + 4x = 6 + 3

==> 6x = 9

<em>dividing both </em><em>sides by 3</em><em>:</em>

==> 2x = 3

==> x = 3/2

Substituting 3/2 for x in equation (i):

==> y = 2(3/2) - 6

==> y = 3 - 6

==> y = -3

Help I don’t know how to find it!
Thepotemich [5.8K]

Answer:

would it be 130?

Step-by-step explanation:

because 40+90=130 then 180-130=50 so 1=50 and that means 3 is 50 too. so then you would subtract 50 from 190 which is 130.
