1252. a) x + 0,6 = 3,5 r) 5x + 7,02 = 12,02 6) 3,5 + x = 19,3 ) 0,82 + 3x = 12,82 B) 5,8 - x = 4,93 A) 4x + 5,47 = 17,47​ тільки а)б)в)

Answer 1

$x + 0.6 = 3.5 \\ x = 3.5 - 0.6 \\ x = 2.9$

$5x + 7.02 = 12.02 \\ 5x = 12.02 - 7.02 \\ 5x = 5 \\ x = 5 \div 5 \\ x = 1$

$3.5 + x = 19.3 \\ x = 19.3 - 3.5 \\ x = 15.8$

$0.82 + 3x = 12.82 \\ 3x = 12.82 - 0.82 \\ 3x = 12 \\ x = 12 \div 3 \\ x = 4$

$5.8 - x = 4.93 \\ x = 5.8 - 4.93 \\ x = 0.87$

$4x + 5.47 = 17.47 \\ 4x = 17.47 - 5.47 \\ 4x = 12 \\ x = 12 \div 4 \\ x = 3$

Answer 2

Let's solve each equation step by step:

a) x + 0.6 = 3.5 To isolate x, we subtract 0.6 from both sides: x = 3.5 - 0.6 x = 2.9

b) 5.8 - x = 4.93 To isolate x, we subtract 5.8 from both sides:

• x = 4.93 - 5.8
• x = -0.87 To solve for x, we multiply both sides by -1 to change the sign: x = 0.87

c) 3.5 + x = 19.3 To isolate x, we subtract 3.5 from both sides: x = 19.3 - 3.5 x = 15.8

d) 0.82 + 3x = 12.82 To isolate x, we subtract 0.82 from both sides and then divide by 3: 3x = 12.82 - 0.82 3x = 12 x = 12 / 3 x = 4

e) 4x + 5.47 = 17.47 To isolate x, we subtract 5.47 from both sides and then divide by 4: 4x = 17.47 - 5.47 4x = 12 x = 12 / 4 x = 3

So, the solutions for each equation are: a) x = 2.9 b) x = 0.87 c) x = 15.8 d) x = 4 e) x = 3
