Susun ulang persyaratan: 3 + 2x = x + 8
Susun ulang persyaratan: 3 + 2x = 8 + x
Pemecahan 3 + 2x = 8 + x
Pemecahan untuk variabel 'X'
3 + 2x + -1x = 8 + x + -1x
Combine like terms: 2x + -1x = 1x 3 + 1x =
8 + x + -1x
Combine like terms: x + -1x = 0 3 + 1x =
8 + 0 3 + 1x = 8
Add '-3' to each side of the equation.
3 + -3 + 1x = 8 + -3
Combine like terms: 3 + -3 = 0
0 + 1x = 8 + -3
1x = 8 + -3
Combine like terms: 8 + -3 = 5
1x = 5
Divide each side by '1'.
x = 5
Simplifying
x = 5
