Equations With Variables on Both Sides

What's the first step?

100

3x + -1 = 5x + 4

Move the variable to one side. Subtract 5x from both sides. -2x + -1 = 4

200

What is the first step? 2x-1=3x+8

Move the variable to one side. So, subtract 2x from both sides. -1=x+8

300

What is the first step? -5x = -8x - 4

Move the variable to one side. So, add 8x to both sides. 3x = -4

400

What is the first step to solve this? 3x + 5x + 2 = 6x - 1

Combine Like Terms. Add 3x + 5x and make it 8x. 8x + 2 = 6x - 1

500

What is the first step? 3(x - 1) = 4x

Use the distributive property. 3x - 3 = 4x

Solve for x

100

Solve for x: 18 = 4x + 2

x = 4

200

Solve for x: -3x - 18 = 21

x = -13

300

Solve for x: 2x + 2 = 5x + 11

x = -3

400

Solve for x: -3 - 4x = 21- 8x

x = 6

500

Solve for x: 2x + 12x - 8 = 11x + 1

x = 3

Solve for y

100

Solve for y: 25 = 3y + 16

y = 3

200

Solve for y: -6y + 24 = 60

y = -6

300

Solve for y: 5y + 30 = 9y + 10

y = 5

400

Solve for y: -9y + 8 = 48 + y

y = -4

500

Solve for y: -6y + 14y - 280 = -9y + -127

y = 9

Solve for m: 3m = -9

m = -3

200

Solve for x: -5x - 6 = -36

x = 6

300

Solve for x: 6x+3=2x-9

x = -3

400

Solve for c: 5 - 4c = 7c + 60

c = -5

500

Solve for n: -2n + n + 4 = 2(n - 10)

n = 8
