Step-by-step explanation:

<u>Step 1: Define</u>

-(12 - 8x) = 5x + 15 - 7x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute negative:                    -12 + 8x = 5x + 15 - 7x
  2. Combine like terms:                   -12 + 8x = -2x + 15
  3. Add 2x on both sides:                -12 + 10x = 15
  4. Isolate <em>x</em> term:                              10x = 27
  5. Isolate <em>x</em>:                                       x = 27/10

Step by step:
2l+2w=282
l=2w-6
Plug in l
2(2w-6)+2w=282
4w-12+2w=282
6w-12=282
6w=282+12
w=294/6
w=49
Then plug in w
2l+2(49)=282
2l+98=282
2l= 184

Solve the equation 2/5x-1=9. Complete each step of the solution and check your solution
Fofino [41]

Answer:

x = 25

Step-by-step explanation:

2/5x - 1 = 9

Add 1 to both sides

2/5x = 10

Multiply by 5 on both sides

2x = 50

Divide by 2 on both sides

x = 25

Check the answer:

Plug in 25 for x

2/5(25) - 1 = 9

10 - 1 = 9

9 = 9

The answer is correct.
