Question

Уравнения 37х= 259 (38 + б)*12=840 14(р-30) = 630 (43 -s) * 17=289

Answer 1

37х=259
х=259:37
х=7

(38+б)*12=840
38+б=840:12
38+б=70
б=70-38
б=32

14(р-30)=630
р-30=630:14
р-30=45
р=30+45
р=75

(43-с)*17=289
43-с=289:17
43-с=17
с=43-17
с=42

Answer 2

37x = 259 To solve for x, divide both sides by 37: x = 259 / 37 x = 7

38 + b * 12 = 840 To solve for b, first subtract 38 from both sides: b * 12 = 840 - 38 b * 12 = 802 Then, divide both sides by 12: b = 802 / 12 b = 66.83

14(r - 30) = 630 To solve for r, first divide both sides by 14: r - 30 = 630 / 14 r - 30 = 45 Then, add 30 to both sides: r = 45 + 30 r = 75

43 + (-s) * 17 = 289 To solve for s, first subtract 43 from both sides: (-s) * 17 = 289 - 43 (-s) * 17 = 246 Then, divide both sides by 17: -s = 246 / 17 -s = 14.47 Finally, multiply both sides by -1 to solve for s: s = -14.47
