Solve the equation 2x + 3 - 5x = 3x + 5 - x.

• -2/5

• -5/2

• 2

• 3

What is the solution of the inequality?

-3 < -(x+9)

• x < -12

• x > 12

• x < -6

• x > -6

8x - 6y = 12

• y = 4/3x - 2

• y = -4/3x + 2

• y = 4/3x + 12

• y = -4/3x - 12

Simplify and combine like term:

3.7x + (0.5 - 6y) + 0.8 - (1.7x + 1 - 2.3y)

• 2x - 8.3y + 2.3

• 5.4x + 8.3y + 2.3

• 2x - 3.7y + 0.3

• 2x + 8.3y - 0.7

Solve the equation for x:

0.2(25x - 40) = 4(0.5x + 1.75)

• -3.5
