Without an equality sign the given expression can't be considered to be an equation.
But if you mean: 3(x+1) = 9 then 3x+3 = 9 and 3x = 9-3 so 3x = 6 => x = 2
(3x - 1)(3x + 19)
One-step equation 3x=12 x-6=5 4/x=7 Multistep equation 3x+8=11 x/7+4=6 4x/7=2
6x + 4 = 3x + 19 3x + 4 = 19 3x = 15 x = 5 Check it. 30 + 4 = 15 + 19 It checks.
if 3x+5=x+19 then x=7
4x plus 7 plus 3x equals 19 plus xx = 2
If you mean 3x+2y = -5 and -2x+3y = -5 then they are straight line equations
y = 3x + 1 y = 3x + 2 y = 3x + 3 y = 3x
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
There is none. 3x+82 is just an expression of numbers. Only equations can be solved. Example: 3x+82 = 10 (This is an equation); 3x = -82; x = 27.3333
Equivalent to what? "3x = 3 + x" is an equation which can be equivalent to other equations, but none is mentioned.
