You can put this solution on YOUR website! 8-2x=30 Since 8 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 8 from both sides.
−2x=−8+30
Add 30 to −8 to get 22.
−2x=22
Divide each term in the equation by −2.
−2x −2 =22 −2
Move the minus sign from the denominator to the front of the expression.
2x 2 =22 −2
Cancel the common factor of 2 the expression 2x 2 .
1 2 x 2 =22 −2
Reduce the expression 2x 2 by removing a factor of 2 from the numerator and denominator.
x=22 −2
Move the minus sign from the denominator to the front of the expression.
x=−22 2
Cancel the common factor of 2 the expression −22 2 .
x=− 11 22 2
Reduce the expression −22 2 by removing a factor of 2 from the numerator and denominator.
x=−11
