-20=-0.5\left(x-7\right)
Multiply -4 and 5 to get -20.
-20=-0.5x+3.5
Use the distributive property to multiply -0.5 by x-7.
-0.5x+3.5=-20
Swap sides so that all variable terms are on the left hand side.
-0.5x=-20-3.5
Subtract 3.5 from both sides.
-0.5x=-23.5
Subtract 3.5 from -20 to get -23.5.
x=\frac{-23.5}{-0.5}
Divide both sides by -0.5.
x=\frac{-235}{-5}
Expand \frac{-23.5}{-0.5} by multiplying both numerator and the denominator by 10.
x=47
Divide -235 by -5 to get 47.
