Answer:
x(2x-3)=43
Step-by-step explanation:
width: 2x-3
length: x
area=length*width
43=x(2x-3)
3x - y = 6 ------------ (1)
y = x - 4 ------------ (2)
From (1) + (2) :
( 3x - y) + y = 6 + (x - 4)
3x - y + y = 6 + x - 4
3x = x + 2
2x = 2
x = 1 ------------- Sub into (2)
y = x - 4
y = 1 - 4
y = -3
Answer: x = 1, y = -3
