X + y = -3
<u>x - y = 13</u>
<u>2x</u> = <u>10</u>
2 2
x = 5
x + y = -3
5 + y = -3
<u>- 5 - 5</u>
y = -8
(x, y) = (5, -8)
the answer of division is 5.2
18 multiplied with t
Product represents multiplication
The coefficient is 18
and to solve, t/18 is also correct
The answer is Q. 78 (pi) cubic meters
