What is the Aquarium size????? If it’s 5L it should be only 1 guppie
<span>add 13.3 + (–7)
= 13.3 - 7 = 6.3
</span>Subtract.
<span>–56 – (–27.07)
</span>= -56 + <span>27.07
= -28.93
</span>simplify
<span>14- (-8)+5 -(-10)
</span>= 14 + 8 + 5 + 10
= 37
The solution of simultaneous equations is x=4 and y = -1.
<h3>What are
Simultaneous equations?</h3>
Simultaneous equations are two or more algebraic equations with the same unknown variables and the same value of the variables satisfies all such equations.
We can solve simultaneous equations by various methods. here we will solve it by elimination method.
Here we have two simultaneous equations
3x -2y = 14 --- (i)
and 4x + 3y = 13---(ii)
Now multiplying (i) by 3 and (ii) by 2 we get
9x -6y = 42 and 8x + 6y = 26.
Now adding both we get
17x = 68 ⇒ x = 68/17 ⇒ x = 4.
Substituting the value of x in (i), we get
3*4 - 2y = 14 ⇒ -2y = 14-12 = 2 = -2/2 ⇒ y = -1.
Therefore, the values of x and y are 4 and -1 respectively .
