3x-8+5x+39+4x+51 = x(3+5+4) + -8 + 39 + 51 = 12x +82
The solution to 79 plus 39 is 118. The solution to 79 minus 39 is 40.
3x-5=3x+5 There is no solution.
x = 0
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
3x + 7 = 46 is an equation. It can be solved as follows: 3x = 39 so x = 13
3x-5
8x = 32 so x = 4
You cannot. 3x + 4 is an expression, not an equation or inequality. There cannot be a solution.
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
The given expression has no solution but it can be simplified to: 5x-1045
3x + 2y + 5 - 3 = 3x + 2y + 2 No further simplification is possible. This is an expression, not an equation so there cannot be a solution.
