Answer:
<u>x=-1.5</u>
Step-by-step explanation:
To solve for x, you need to rearrange so the x is on one side of the "=" by itself.
So To do that, first you need to subtract 1/4 on both sides of the "=". This leaves you with 1/2+x=-3/4-1/4. You can simplify the -3/4-1/4 to -1 (-4/4). So, you now have 1/2+x=-1.
The next step is to subtract 1/2 on both sides of the "=". This leaves you with x=-1-1/2. Again, you can simplify the -1-1/2 to -3/2 which can be written as -1.5. So, you now have x=-1.5, which is the final answer.
The question may ask you to write your answer in the form of a fraction, in which case your answer x=-3/2. If the questions wants it written as a mixed number, your answer would be -1 1/2.

Answer:
( x ,y ) = ( 8 , 22 )
( x , y ) = ( 22 , 8 )
Step-by-step explanation:
Let 1st no. be x and second no. be y
<em>Given</em><em> </em><em>:</em><em>-</em><em> </em> sum of the nos. is 30
x + y = 30 ... ( i )
also, their product is 176
xy = 176 ... ( ii )
putting value of x from ( i ) in ( ii )
( 30 - y )y = 176
30y - y² = 176
y² - 30y + 176 = 0
y² - 22y - 8y + 176 = 0
y ( y - 22 ) - 8 ( y - 22 ) = 0
( y - 22 ) ( y - 8 ) = 0
• y - 22 = 0
y = 22
also,
• y - 8 = 0
y = 8
So, for y = 22 , x = 30 - y = 8
for ,y = 8 , x = 22
