Question

Please solve these 2 ;-;

y = 2x – 6
y = –4x + 3

Answer 1

`- 4x + 3 = 2x - 6 \\ 6x = - 9 \\ 2x = - 3 \\ x = - 1.5`

Answer 2

x = 3/2 | y = -3

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

dividing both sides by 3:

==> 2x = 3

==> x = 3/2

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

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

==> y = 3 - 6

==> y = -3
