Solve for x.<br><br> 2/3(x−7)=−2
zaharov [31]
2/3x - 14/3 = -2
3(2/3x - 14/3) = -2(3)
           2x - 14 = -6
                   2x = -6 + 14
                   2x = 8
                     x = 8/2
                     x= 4

hope this helps :)

Find x<br> 25<br> 7<br> х<br> I need help
Murljashka [212]

Answer:

24 = x

Step-by-step explanation:

You use Pythagorean theorem. Since the normal equation is a^{2} + b^{2} =c^{2}, you already have the c^{2} and another side which can be a^{2} or b^{2}.

Because you have the hypotenuse and a side , your equation looks like this now: 7^{2} +b^{2} = 25^{2}

and when you solve for be you just subtract 25^{2} -7^{2} to get 24.
