For this case we have a system of two equations with two unknowns:
We follow the steps below:
We add the equations:
We divide between 9 on both sides of the equation:
We substitute the value of "x" in the first equation and find the value of y:
Thus, the solution of the system is: (3, -1)
Answer:
(3, -1)
The car is 1.4m (140 cm) tall and 3.5 (350 cm) long.

7: The football traveled 90 yds total 50+40=90
8: Answer: yes because 12²=144 9²=81 add them and get 225 and 15×15=225
9: x=15ft a^2+b^2=c^2 8^2+b^2=17^2 b^2+64=289 b^2=225 b=15
10: The cat is 12 feet above the ground, and Peter has to put the base of his ladder 9 feet away from the tree because of mud. If we consider a right-angled triangle, in which the height is 12 feet, base is 9 feet.
