X=area of the country A
y=area of the country B
we saggest this system of equations:
x+y=178,973
x=y+373
we solve this system of equations by substitution method.
(y+373)+y=178,973
2y=178,973-373
2y=178600
y=178,600/2=89,300
x=y+373
x=89300+373=89,673
answer:
area of the country A=89,673 Km²
area of the country B=89,300 Km²
To check
The combined land area of the countries A and B is =89,673 Km²+89,300 Km²=178,973 Km²
Country A (89,673 Km²) is 373 Km² more larger than country B (89,300 Km²).
89,673 Km²=89,300 Km²+373 Km²

Answer:
(3x-7) (x-7)
Step-by-step explanation:
Answer:
you mean like this :))
-5x +7 = Y
Step-by-step explanation:
3x - y = 8x - 7
<=>3x - 8x = y - 7
<=>-5x = y - 7
<=>-5x + 7 = Y
