Answer:

(-2/3, -13/3)

Explanation:

Given the expressions;


y= 2x - 3\\y = ((1)/(2) )x - 4

Equating both expressions;


y=y\\2x-3=(1)/(2)x-4\\

Collect the like terms:


2x-(1)/(2)x=-4+3\\(3x)/(2)=-1\\3x=-2\\x=(-2)/(3)

Substitute
x=(-2)/(3) into any of the expressions to get 'y'


Recall\ y= 2x-3\\y=2((-2)/(3) )-3\\y=(-4)/(3)-3\\y=(-4-9)/(3) \\y=(-13)/(3)

Hence the solution to the equation is (-2/3, -13/3)
