x + 7y = 33 multiply through by 3: 3x + 21y = 99 Subtract the second equation from the above equation: 23y = 92 So y = 4 Substituting this value of y in the first equation, x + 28 = 33 ie x = 5 The solution is (x,y) = (5,4)
−39x−6
If: 3x+6 = 12 Then: x = 2
You cannot. 3x + 4 is an expression, not an equation or inequality. There cannot be a solution.
3x - 2 = 9 3x = 9 + 2 = 11 x = 11/3
3x+5 Solution- 3x+5=0 3x= (-5) x= (-5)/3
x + 7y = 33 multiply through by 3: 3x + 21y = 99 Subtract the second equation from the above equation: 23y = 92 So y = 4 Substituting this value of y in the first equation, x + 28 = 33 ie x = 5 The solution is (x,y) = (5,4)
−39x−6
There is no solution since there is no equation, just an expression.
Solve 3x = 33
If: 3x+6 = 12 Then: x = 2
Assuming the equation is: 3x - 1 = 0 Then... 3x = 1 x = 1/3
If you mean: 3x-9 = 12 then the value of x is 7
You cannot. 3x + 4 is an expression, not an equation or inequality. There cannot be a solution.

A solution to an question makes the equation true. For example a solution to the equation 3x = x + 6 is x = 3, since 3(3) = 3+6.
3x - 2 = 9 3x = 9 + 2 = 11 x = 11/3
