Solving Equations

100

Solve for x.

108 = 3x - 60

56

200

(-67) - 7x = 24

-13

300

-3x + 18 = 8x + 106

x = -8

400

Solve for x.

-x + 255 = -9x + 383

x = 16

500

Solve for x.

(1/5)x + 18 = 2x - 36

x = 30

Slope

100

Identify the slope and y-intercept in the equation.

y = 17 + -6x

slope = -6

y-int = 17

200

Identify the slope and y-intercept in the equation.

y = -88x - 121

slope = -88

y-int = -121
