8 - 10 + 7 = 5 x = 4
9 plus 7 equals 144. Generally, x plus y = x(x+y).
so 3x + 2 = x + 12 ie 2x = 10 x =5
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
x + 3x - 10 = 5 - 4 4x - 10 = 1 4x = 1 + 10 x = 11/4
X= 5
x=5
If: x+10 = 15 then x = 5
If your question was 2X + 5 =10. X equals what? Then X=2.5
5
-1
x = -10
2x+x-5 = 10 2x+x = 10+5 3x = 15 x = 5 and y = 0
(x-5)(x-2) x=5 and 2
It is a linear equation in x. It has a solution, which is x = -5
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
If 3x = x + 10 then 2x = 10 and x = 5
