2x+y-3z=12
2x=4z-y
x=2z-y/2
Answer:
7800
Step-by-step explanation:
Were there angles given? you just didn't quite give enough information to do this quickly. But I'll try, so a^2 plus b^2 is 400, and a+b is over 20, so we know that much. Therefore we find two numbers that equal 400 when squared and added and are more than 20. And since it's isosceles the other two sides must equal, the number you end up getting is 14.14213561 for the two sides. Then to find area you are gonna square that since it's base times height and get 200 then divide that by two, which is 100 units^2.
Step 1: <span>Simplify both sides of the equation.
<span>Step 2: Multiply both sides by 3/(-1).
Answer: </span>x= <span>1</span>
