2/3 is equal to 4/6, all you have to do is multiply the numerator and the denominator. I did by 2.
"Enlargement" here implies that the two pentagons are similar. Because of similarity, the following equation of ratios must be true: 7/15 = x/7. Then 15x=49, and x = 49/15 = 3.27 cm, approximately.
Rounded to the nearest tenth, that comes to 3.3 cm.
X + 2y = 8
x = -2y + 8....so we sub -2y + 8 for x in the other equation
2x + y = 7
2(-2y + 8) + y = 7
-4y + 16 + y = 7
-3y = 7 - 16
-3y = - 9
y = -9/-3
y = 3
x = -2y + 8
x = -2(3) + 8
x = -6 + 8
x = 2
solution is (2,3)
