You don't "solve" an expression. You can solve an equation; an expression can be simplified or otherwise manipulated, and if you know the value of "x" (in this case), you can evaluate its value.
x=-1 ^ how do you know?
X=1
The solution to the equation 2x plus 2 is 2(x + 1).
5x+3 = x+4 5x-x = 4-3 4x = 1 x = 1/4 Thats not even close to how you solve it. First of all the equation is written 5^(x+3)=x+4. Simple Logarithms are needed to solve.
x = 3.5
Yes but not me
To solve for x, we'd have to know what this expression equals.
If: x+1+2x = 1x+5 Then: x = 2
5X-3 - X-1 + X + 6 The answerdepends on value of X
8+-1= 7 x=-1
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
x + 1= -y implies x - y = 1
x=-1 ^ how do you know?
Y equals 1 and X equals 1
i have no clue what the answer is
1 + 3x - x = x - 4 + 2x 1 + 4 = x + 2x - 3x + x 5 = x
The answer would be no solution. x+1=x+2. Subtract 1 from both sides x=x+1. Subtract x from both sides. 1 does not = 0
