Whiteboard Activity One Step Equations

X – 2.3 = 4.7 X = 7

X + 8 = 14.1 X = 6.1

X / 1.2 = =7 X= -8.4

X + 3.9 = 0.7 X = -3.2

-6.3x = -8.19 X = 1.3

32.663 = x + 11.363 X = 21.3

X – 25.4 = -44.8 X = 19.4

28.8 = 18x X = 1.6

X – 18 = -36.6 X = -18.6

-165.832 - -10.91x X = 15.2

Translate each verbal expression into an algebraic expression, then solve

the sum of a number and 2.62 is 6.37 X + 2.62 = 6.37 X = 3.75

¾ of a number is 9 3/4x = 9 X = 12

the quotient of some number and -1.8 is 7.2 x/-1.8 = 7.2 X = -12.96

the difference of a number and 2.4 is equal to -1.2 X – 2.4 = -1.2 X = 1.2

a number squared is 225. X2 = 225 X = 15
