AnnZ [28]

Answer:

see below

Step-by-step explanation:

1. 2m = 24

Divide each side by 2

2m/2 = 24/2

m = 12

2. y – 9 = 30

Add 9 to each side

y-9+9 = 30+9

y = 39

3. X/4 = 12

Multiply each side by 4

x/4*4 = 12*4

x = 48

4. k + 12.5 = 30

Subtract 12.5 from each side

k+12.5-12.5 = 30-12.5

k =17.5

5. 3r = 15.3

Divide by 3

3r/3 = 15.3/3

r =5.1

5. -[-2(x-4) - |1-3|] = -2x18
irina [24]

Solving the expression  -[-2(x-4) - |1-3|] = -2x18 we get value of x: x=\frac{3}{19}

Step-by-step explanation:

We need to solve the equation -[-2(x-4) - |1-3|] = -2x18 and find value of x

Solving:

-[-2(x-4) - |1-3|] = -2x18

Multiply -2 with terms inside the bracket

-[-2x+8 - |1-3|] = -2x18

Solving |1-3| we get |-2|=2

-[-2x+8 - 2] = -2x18

-[-2x+6] = -2x18

Multiply (-) sign with terms inside the bracket

+2x-6 = -2x18

Multiply 2x with 18

2x-6 = -36x

Add 36x on both sdides

2x-6+36x =0

38x-6 =0

Add 6 on both sides:

38x =6

Divide both sides by 38

x=\frac{6}{38}

Simplifying:

x=\frac{3}{19}

So, Solving the expression  -[-2(x-4) - |1-3|] = -2x18 we get value of x: x=\frac{3}{19}
