Question

14х=-42 2х-16=0 8х-17=23 5х=210+12х

Answer 1

$14x = - 42 \\ x = - 42 \div 14 \\ x = - 3$

$2x - 16 = 0 \\ 2x = 0 + 16 \\ 2x = 16 \\ x = 16 \div 2 \\ x = 8$

$8x - 17 = 23 \\ 8x = 23 + 17 \\ 8x = 40 \\ x = 40 \div 8 \\ x = 5$

$5x = 210 + 12x \\ 5x - 2x = 210 \\ 3x = 210 \\ x = 210 \div 3 \\ x = 70$

Answer 2

Let's solve each equation step by step:

1. 14x = -42: To solve this equation, we divide both sides by 14: 14x/14 = -42/14 x = -3

2. 2x - 16 = 0: To solve this equation, we add 16 to both sides: 2x - 16 + 16 = 0 + 16 2x = 16 Divide both sides by 2: 2x/2 = 16/2 x = 8

3. 8x - 17 = 23: To solve this equation, we add 17 to both sides: 8x - 17 + 17 = 23 + 17 8x = 40 Divide both sides by 8: 8x/8 = 40/8 x = 5

4. 5x = 210 + 12x: To solve this equation, we subtract 12x from both sides: 5x - 12x = 210 + 12x - 12x -7x = 210 Divide both sides by -7: -7x / -7 = 210 / -7 x = -30

Therefore, the solutions for the given equations are: x = -3, 8, 5, -30.
