The x value for equation x+4= 4 is x=0 and the x value for equation x-1= -3 is x= -2.
<u>Step-by-step explanation:</u>
- The equations shown are algebraic equations with an unknown variable 'x'.
- To solve for x, perform certain operations on both sides of the equation separated by an equal to symbol.
- For this, bring x alone on one side of the equation and constants on other side of the equation.
These are steps which must be followed for solving the given equation.
The given equation is x+4 = 4
Therefore, to remove the 4 on the left side of the equation, you need to add -4 on both sides of the equation.
<u>Adding -4 on both sides,</u>
x+4-4 = 4-4
x = 0
Therefore, the value of x is 0.
The given equation is x-1 = -3
Therefore, to remove the -1 on the left side of the equation, you need to add +1 on both sides of the equation.
<u>Adding +1 on both sides,</u>
x-1+1 = -3+1
x = -2
Therefore, the value of x is -2.
