Question

A) 9,7-2(x-3,6)=10,1-x б) 13,8+3(9,6-X)=12,2-4X в)16M+8,3=22,3-2(M-2) г)3,2+9m=1,3-m

Answer 1

а)9,7-2(х-3,6)=10,1-х

9,7-2х+7,2=10,1-х

-2х+х=10,1-9,7-7,2

-х=-6,8

х=6,8

б)13,8+3(9,6-х)=12,2-4х

13,8+28,8-3х=12,2-4х

-3х+4х=12,2-13,8-28,8

х=-30,4

в)16м+8,3=22,3-2(м-2)

16м+8,3=22,3-2м+4

16м+2м=22,3+4-8,3

18м=18

м=18:18

м=1

г)3,2+9м=1,3-м

9м+м=1,3-3,2

10м=1,9

м=1,9:10

м=0,19

Успехов!!!!

Answer 2

To solve each equation, follow these steps:

A) 9.7 - 2(x - 3.6) = 10.1 - x

Step 1: Distribute the -2 to terms inside the parentheses: 9.7 - 2x + 7.2 = 10.1 - x

Step 2: Combine like terms: 16.9 - 2x = 10.1 - x

Step 3: Move all terms with 'x' to one side and the constant terms to the other side: -2x + x = 10.1 - 16.9 -x = -6.8

Step 4: Solve for 'x' by multiplying both sides by -1: x = 6.8

B) 13.8 + 3(9.6 - x) = 12.2 - 4x

Step 1: Distribute the 3 to terms inside the parentheses: 13.8 + 28.8 - 3x = 12.2 - 4x

Step 2: Combine like terms: 42.6 - 3x = 12.2 - 4x

Step 3: Move all terms with 'x' to one side and the constant terms to the other side: -3x + 4x = 12.2 - 42.6 x = -30.4

C) 16M + 8.3 = 22.3 - 2(M - 2)

Step 1: Distribute the -2 to terms inside the parentheses: 16M + 8.3 = 22.3 - 2M + 4

Step 2: Combine like terms: 16M + 2M = 22.3 + 4 - 8.3

Step 3: Combine constants: 18M = 18

Step 4: Solve for 'M': M = 18 / 18 M = 1

D) 3.2 + 9m = 1.3 - m

Step 1: Add 'm' to both sides: 3.2 + 10m = 1.3

Step 2: Subtract 3.2 from both sides: 10m = 1.3 - 3.2

Step 3: Combine constants: 10m = -1.9

Step 4: Solve for 'm': m = -1.9 / 10 m = -0.19

The solutions for each equation are: A) x = 6.8 B) x = -30.4 C) M = 1 D) m = -0.19
