Answer:
x = 3, x = 4
Step-by-step explanation:
Given
= 14 - 2x ( multiply through by x , x ≠ 0 )
24 = 14x - 2x² ( subtract 14x - 2x² from both sides )
2x² - 14x + 24 = 0 ( divide through by 2 )
x² - 7x + 12 = 0 ← in standard form
(x - 3)(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 4 = 0 ⇒ x = 4
Answer:
x=20
Step-by-step explanation:
45+4x=6x+5
45=2x+5
40=2x
20=x
x=20
Then x+y=52....................(1)
<span>and 2x + 4y= 148..........................(2) </span>
<span>multiplying equation (1) by 2 </span>
<span>we get </span>
<span>2x +2y = 104............................(3) </span>
<span>subtracting equation(3) from equation (2) </span>
<span>2y=44 </span>
<span>y=22 </span>
<span>that is x=52-22=30 </span>
<span>there are 30 emus and 22 wombats</span>
