Using basic algebra we can solve this problem. First we need to write out the problem:
5-32+2w = -7
-27+2w = -7
2w = 20
w = 10
w=10
If I am correct, 9 plus 7 equals 112.

9 plus 7 equals 144. Generally, x plus y = x(x+y).
2n plus 7 equals 19 2n equals 12 n equals 6
w=10
It is an equation and the value of w is 3 2w - 11 + 4w = 7 6w - 11 = 7 6w = 7 + 11 6w = 18 w = 3
To solve the system of equations: ( w + x + y + z = 2 ) ( 2w - x - y + 2z = 7 ) ( 2w + 3x + 2y - z = -2 ) ( 3w - 2x - y - 3z = -2 ) You can use methods such as substitution or elimination. Solving these equations yields the values of ( w, x, y, ) and ( z ). After performing the calculations, the solution is ( w = 2, x = 1, y = -1, z = 0 ).
-2w+14+10w=348w=20w=2.5
It equals 24.

It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
If I am correct, 9 plus 7 equals 112.

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
