(x+70)/(180)=(x)/(20)
Multiply each term in the equation by 180.
(x+70)/(180)*180=(x)/(20)*180
Simplify the left-hand side of the equation by canceling the common factors.
x+70=(x)/(20)*180
Simplify the right-hand side of the equation by simplifying each term.
x+70=9x
Since 9x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 9x from both sides.
x+70-9x=0
Since x and -9x are like terms, add -9x to x to get -8x.
-8x+70=0
Since 70 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 70 from both sides.
-8x=-70
Divide each term in the equation by -8.
-(8x)/(-8)=-(70)/(-8)
Simplify the left-hand side of the equation by canceling the common factors.
x=-(70)/(-8)
Simplify the right-hand side of the equation by simplifying each term.
x=(35)/(4)
(35)/(4)
The approximate value of (35)/(4) is 8.75.
8.75
