<u>ANSWER:
</u>
The value of x after evaluating the given equation x + 6 - 5 = 8 - 2 is 5.
<u>SOLUTION:
</u>
Given, equation in one variable is x + 6 – 5 = 8 – 2
And, now, we have to find the value of the variable x in the equation by solving the given equation.
So, let us solve the given equation for x.
Then, x + 6 – 5 = 8 – 2
x = 8 – 2 – (6 – 5) [sending all the numerical terms on left side to the right side.
x = 8 – 2 – 6 + 5
x = 8 + 5 – 2 – 6
x = 13 – 8 = 5
Hence, the value of x after evaluating the given equation is 5.
Answer:
1.) 10
2.) 14
Step-by-step explanation:
Answer:Let the two unknown numbers be x and y.
So, x-y=40 ........Equation 1
And 0.3(x)= 37.5/100 (y)
From equation 1, x=40+y
Now, multiply through by 100 in equation 2.
We have,
30x = 37.5 (y)
We can multiply through by 10 again,so that the number on the L.H.S becomes a whole number.
Therefore, we have
300x = 375 (y)
Put "x=40+y" in the equation above
That is, 300 (40+y) = 375 (y)
1200 + 300y = 375y
1200 = 375y - 300y
1200 = 75y
Divide both sides by 75 to get your y
Therefore, y =16
From equation 1, we had x= 40 + y
Therefore X = 40 + 16
X= 56
Therefore the two unknown numbers are 56 and 16 respectively.
