Question

1)4x-5(x-4)=11 2)7+2(-x+2)=-6x-2 Помогите с подробным решением

Answer 1

4х-5х+20=11
4х-5х=11-20
х=-9
2) 7-2х+4=-6х-2
-2х+6х= -2-7-4
4х=-13
х=-3.25

Answer 2

4x-5x+20=11
-x=11-20
x=9
7-2x+4=-6x-2
-2x+6x=-2-4-7
4x=-13
x=-13:4
x=-3,25

Answer 3

Problem 1: 4x - 5(x - 4) = 11

To solve this equation, we will simplify and then solve for x step by step.

Step 1: Distribute the -5 to the terms inside the parentheses: 4x - 5x + 20 = 11

Step 2: Combine like terms: -x + 20 = 11

Step 3: Move the constant term to the other side of the equation by subtracting 20 from both sides: -x = 11 - 20 -x = -9

Step 4: Multiply both sides of the equation by -1 to isolate x: x = -(-9) x = 9

Therefore, the solution to the equation 4x - 5(x - 4) = 11 is x = 9.

Problem 2: 7 + 2(-x + 2) = -6x - 2

To solve this equation, we will simplify and then solve for x step by step.

Step 1: Distribute the 2 to the terms inside the parentheses: 7 - 2x + 4 = -6x - 2

Step 2: Combine like terms: 11 - 2x = -6x - 2

Step 3: Move the variable terms to one side of the equation and the constant terms to the other side: -2x + 6x = -2 - 11 4x = -13

Step 4: Divide both sides of the equation by 4 to isolate x: x = -13/4

Therefore, the solution to the equation 7 + 2(-x + 2) = -6x - 2 is x = -13/4.
