Question

14х=-42
2х-16=0
8х-17=23
5х=210+12х

Answer 1

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

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

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

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