-1
substitute x = -3, so you get 2(-3) + 5 = -`

Answer:
y = 0, -4
Step-by-step explanation:
1) Factor out the common term 3y.

2) Solve for y.
<em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>0</u></em><em><u>,</u></em><em><u> </u></em><em><u>-4</u></em>
<em><u>Therefor</u></em><em><u>,</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>0</u></em><em><u>,</u></em><em><u> </u></em><em><u>-4</u></em><em><u>.</u></em>
Answer:
42
Step-by-step explanation:
Let total no. of trees be 'X'
Lemon are (1/6) of X = X/6
Orange are (1/2) of X = X/2
Difference is 14
X/2 - X/6 = 14
Lcm is 6
(3X-X)/6 = 14
2X = 14×6
X = 42
7x + 4 = x - 2 -- (1)
To rewrite the equation above as a system, we simply let (1) be equal to y, i.e.
7x + 4 = x - 2 = y -- (2)
Recall from the rule of transitivity: If a = b = c, then this implies that a = c & b = c. From this, we have (2) to be expressed as
y = 7x + 4 -- (i)
y = x - 2 -- (ii)
Note: (i) & (ii) are both regarded as a system of linear equation which can be evaluated simultaneously.
