Help pls 7x+3(5-3x)=5

x = 5

Step-by-step explanation:

7x + 3(5-3x) = 5

7x + 15 - 9x = 5

-2x + 15 = 5

-2x = 5 - 15

-2x = -10 ÷ 2

x = 5

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
