Answer:
<em>(D). x = 2 , y = - 5</em>
Step-by-step explanation:
A = - 8 + 48 = 40
= -76 + 156 = 80
= 104 - 304 = - 200
<em>x =</em>
= <em>2</em>
<em>y =</em>
= <em>- 5</em>
<u><em>( 2, - 5 )</em></u>
Answer:
x = 17
Step-by-step explanation:
First, let's turn this into an equation:
twenty more ( +20 ) than four times a number ( 4x ) is equal ( = ) to the difference ( - ) between 139 and 3 times the number ( 3x ).
4x + 20 = 139 - 3x
Now let's solve:
Subtract 20 from each side:
4x = 119 - 3x
Add 3x to each side:
7x = 119
Divide each side by 7:
x = 17
