The width of George Washington's face would be f = 40
The question tells us to find the width of Washington’s face, using the variable f. The equation that we are to use in order to find this is given as 4f - 100 = 60
The next thing would be for us to take the like terms of the equation
4f - 100 = 60
4f = 60 + 100
The sign next to 100 changed to positive because it went over the equal to sign
4f = 160
divide through by 4
f = 160 / 4
f = 40
Hence the width of the face of George Washington is given as 40 ft
