3X - 16 = 2
add 16 to both sides
3X - 16 + 16 = 2 + 16
3X = 18
divide both sides integers by 3
(3/3)X = 18/3
X = 6
----------------check in original equation
3(6) - 16 = 2
18 - 16 = 2
2 = 2

How do you solve 5x plus 2-3x equals 16?
5x + 2 - 3x = 16 Combining terms: 2x + 2 = 16 Subtract 2 from both sides: 2x = 14 Divide both sides by 2: x = 7
How do you solve 3x squared plus 2x equals 16?
3x2 + 2x = 16 ∴ 3x2 + 2x - 16 = 0 ∴ 3x2 - 6x + 8x - 16 = 0 ∴ 3x(x - 2) + 8(x - 2) = 0 ∴ (3x + 8)(x - 2) = 0 ∴ x ∈ {-8/3, 2}
Solve 3x-5 equals 2y?
3x - 5 = 2y3/2X - 5/2 = y
What is 3x plus 16 equals 22?

How do you solve 5x plus 2-3x equals 16?
5x + 2 - 3x = 16 Combining terms: 2x + 2 = 16 Subtract 2 from both sides: 2x = 14 Divide both sides by 2: x = 7
How do you solve 3x squared plus 2x equals 16?
3x2 + 2x = 16 ∴ 3x2 + 2x - 16 = 0 ∴ 3x2 - 6x + 8x - 16 = 0 ∴ 3x(x - 2) + 8(x - 2) = 0 ∴ (3x + 8)(x - 2) = 0 ∴ x ∈ {-8/3, 2}
15x - 8 - 3x equals 16?
Set up the equation and solve: 15x - 8 - 3x = 16 (next add 8 to each side) 15x - 3x - 16 + 8 (next simplify) 12x = 24 (next divide both side by 12 to solve for x) x = 2
3x - 2 plus 5 equals 16?
3x - 2 + 5 = 16 3x + 3 = 16 3x = 13 x = 13/3 ~ 4.333

How do you solve this equation 3x plus 2y equals 12 solve for y?
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
Solve 3x-5 equals 2y?
3x - 5 = 2y3/2X - 5/2 = y
Solve-3x-2 equals 2x plus 4 for x?
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
How do you solve the equation 3x-2 equals 2x plus 3?
3x-2 = 2x+3 3x-2x = 3+2 x = 5
What is 3x plus 16 equals 22?
3x + 16 = 22 3x = 6 x = 6/3 x = 2
How do you solve 5X plus 2 equals 3X-6?
5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4
