Solve for n: 10 + 3n = 5n - 8

• n = 9

• n = -9

• n = -1

• n = 1

What is the solution to the equation below? 12y - 5 = 7y

• y = 1

• y = -1

• y = 5/5

• y = -5/5

Solve the equation: 4(3k + 2) = -34

• k = -3.5

• k = 2.5

• k = -2.5

• k = 3.5

Three times a number decreased by four is equal to the number increased by five.

• 3x - 4 = x + 5

• 3x + 4 = x - 5

• x/3 - 4 = x + 5

• x² - 4 = x + 5
