Step-by-step explanation:
The answer to this would be the 3rd option
Answer:
You need to add: <span> <span>x2</span>+x+6</span>
Explanation:
Let the unknown part be represented by A
Then we have: <span> 3x−7+A=<span>x2</span>+4x−1</span>
Subtract <span>3x</span> from both sides
<span>−7+A=<span>x2</span>+4x−3x−1</span>
but <span>4x−3x</span> is giving:
<span>−7+A=<span>x2</span>+x−1</span>
Add 7 to both sides
<span>A=<span>x2</span>+x+6</span>
So you need to add: <span><span>x2</span>+x+<span>6</span></span>
check the picture below.
make sure your calculator is in Degree mode.
The first given equation is:
4y + 1 = x .......> equation I
The second given equation is:
2x = 5y .......> equation II
Substitute with equation I in equation II to get the value of y as follows:
2x = 5y
2(4y+1) = 5y
8y + 2 = 5y
8y - 5y = -2
3y = -2
y = -2/3
Substitute with the value of y in equation I to get the value of x as follows:
x = 4y + 1
x = 4(-2/3) + 1
x = -5/3
Based on the above calculations:
x = -5/3
y = -2/3
