Solving Equations using basic operations

100

Solve for r: r-21= -37

r = -16

200

Solve for r: r + (-1/2) = -3/4

r = -1/4

300

Solve for x: 6x = -42

x = -7

400

Solve for a: (5/2)a = -25

a = -10

500

Solve for r: 5 = r/2

r = 10

Solving Multi-Step Equations

100

Solve for p: 4p - 7 = 5

p = 3

200

Solve for v: 6 = 4v +2

v = 1

300

Solve for c: (c/-4) -8=-42

c = 136

400

Solve for y: (y/3) + 6=-45

y = -153

500

d = 11

Solving Equations with a Variable on Each Side

100

Solve for n: n-2=4 - 2n

n = 2

200

Solve for q: 3-4q = 10q +10

q = -0.5

300

Solve for t: 5t - 9 = -3t +7

t = 2

400

Solve for d: 3(1 +d)-5 = 3d -2

All numbers (the same on both sides)

500

Solve for f: 4(f -2) = 4f

No solution (0 = 8)

Solving Equations & Formulas

100

Solve for x: 5x = y

x= y/5

200

Solve for x: yx - a = cx

x = a/y-c

300

Solve for y: ay - b = c

y= (b + c)/a

400

Solve for y: 3x - 4y = 7

y= (3x - 7)/4

500

Solve for m: y = mx + b

 m = (y-b)/x
