The picture is kind of grainy but it looks like:
4u = 56
Add 4's to both sides:
4u/4 = 56/4
cross out both 4's on left side and divide on the right:
u = 14
Answer:
<em>- 2 </em>
<em> + 7x²y - 24y² </em>
Step-by-step explanation:
( 5 - 5x²y + 9y² ) - ( 7 - 12x²y + 33y² ) =
5 - 5x²y + 9y² - 7 + 12x²y - 33y² =
( 5 - 7 ) + ( - 5x²y + 12x²y ) + ( 9y² - 33y² ) =
<em>- 2 </em><em> + 7x²y - 24y²</em>
You just plug in both numbers in the x of the equation and then multiply by 4 and subtract by the 3
120 is your answer cause half 120 is 60
