If you mean sqrt (3w +13) = sqrt(5w-7) with all terms under the radical, then just square both sides. then; 3w+13 = 5w-7 ( subtract 3w from each side ) 13 = 2w-7 ( add 7 to both sides ) 20 = 2w 10 = w

7+3w-13x

3w + 12

If: 3w-17 = 4 Then: w = 7

p is obviously zero because any number x plus 0 equals itself.

you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8

7+6

n= -2

Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7

It does not help you.

v = -6

If n + 7 = 12, then n = 12 - 7

It is not possible to solve a single linear equation in two variables.

-3+x=7. x=10

You cannot solve one linear equation in two unknown variables.

c= -2 2/7 OR -2.285714

y=7+x =x=7-x

x= -8

8+-1= 7 x=-1

6+8=14

Set up the equation and solve: 13 = 7 + s (next subtract 7 from each side of the equation to solve for s) 6 = s
