Question

Solve for x.

Answer 1

1. x=1 
5x=4+x
4x=4
x=1

2. x=3/4 or 0.75
2/3x=1/2
2x=1 1/2
x=3/4

3. x=1
3x-2x+4=15/3
x+4=15/3
x=1

4. x=5
4x+7=2x+17
2x+7=17
2x=10
x=5

5. x=20
.5x=10
x=20

Answer 2

1.  5(x) - [4 + x] = ? 
      4(x - 1)
       4 = ?
          x - 1 = ? 
           Now let's add ( + ) to your sides 
                       Answer: x = 1 

2.  $\frac{2}{3} (x) - \frac{1}{2}$ = ? 
     $\frac{1}{2}$
     $\frac{2}{3} (x) - \frac{1}{2}$ = ? 
     $\frac{2}{3}$
    L denominator = 3
    R denominator = 2
   Put them together it would be 6 
   $\frac{4(x) - 3}{6 }$ = ? 
   4(x) - 3 = ? 
  Let's add 3 from your sides 
 Repeat the process but let's divide by 4 
  4(x) = 3 
 Answer   x = $\frac{3}{4}$

3. 3(x) - 2(x) + 4 - $\frac{15}{3}$ = ? 
   $\frac{5}{1}$
   x + 4 - 5 = ? 
  x - 1  = 0
 Now, let add the number 1 from each sides 
  Answer: x = 1 

4.  4(x) + 7 - 2(x) +  17 = ? 
    2(x - 5)
    2 = ?
    x - 5 = 0
   Replace the subtraction symbol and make it a addition symbol ( but by 5)
  Answer: x = 5 

5.    .5(x) - 10 = ? 
       $\frac{1}{2}$
       $\frac{1}{2} (x) - 10$ = ?
       $\frac{10(2) }{2}$
       $\frac{x - 20}{2}$
        x - 20 =  0 
Add the number 20 to each of your sides after replacing the subtraction symbol to a addition symbol 
    Answer: x = 20
