|
Keep the Variable on the left side and constant on the right side of the equality. Then, Solve for x.
x+2= 2x+1 x+2-2= 2x+1-2 x= 2x-1 x-2x= 2x-x-1 -x= -1 x= 1
Use inverse operation to solve
Solve the equation by keeping the variable on one side and the variable on the other.
x+5= 2 x+5-5 = 2-5 x= - 3
Keep the variable on the left side and the constant on the right side of the equality. Then, Solve for x
Solve the equation by keeping the variable on one side and the variable on the other.
Use inverse operation to solve
2x+5= x+\\frac{1}{2} 2x+5= \\frac{2x+1}{2} 2(2x+5)= 2x+1 4x+10= 2x+1 4x+10-10= 2x+1-10 4x= 2x-9 4x-2x= 2x-2x-9 2x= -9 x= \\frac{-9}{2}
Solve the equation by keeping the variable on one side and the variable on the other.
