4(+2)=8+4

1.Distribute

4(+2)=8+4

4+8=8+4

2.Rearrange terms

4+8=8+4

4+8=4+8

3.Subtract 8 from both sides of the equation

4+8=4+8

4+8−8=4+8−8

4.Simplify

  1. Subtract the numbers

4+8−8=4+8−8

4=4+8−8

2.Subtract the numbers

4=4+8−8

4=4

5.Subtract 4 from both sides of the equation

4=4

4−4=4−4

6.Simplify

1.Combine like terms

4−4=4−4

0=4−4

0=0

The Answer is 0=0.

[tex] \frac{1}{5}(25 - 5a) = 4 - a [/tex]

Rearrange terms

[tex] \frac{1}{5}(25 - 5a) = 4 - a \\ \frac{1}{5}( - 5a + 25) = 4 - a \\ [/tex]

2.Combine multiplied terms into a single fraction

[tex] \frac{1}{5}( - 5a + 25) = 4 - a \\ \frac{1( - 5a + 25)}{5} = 4 - a [/tex]

3.Multiply by 1

[tex] \frac{1( - 5a + 25)}{5} = 4 - a \\ \frac{ - 5a + 25}{5} = 4 - a [/tex]

4. Rearrange terms

[tex] \frac{ - 5a + 25}{5} = 4 - a \\ \frac{ - 5a + 25}{5} = - a + 4 [/tex]

5.Add  to both sides of the equation

[tex] \frac{−5+25}{5} = - a + 4 \\ \frac{−5+25}{5} + a= - a + 4 + a [/tex]

6. Simplify

Find common denominator

[tex] \frac{ - 5a + 25}{5} + a = - a + 4 + a \\ \frac{ - 5a + 25}{5} + \frac{5a}{5} = - a + 4 + a [/tex]

2.Combine fractions with common denominator.

[tex] \frac{ - 5a + 25}{5} + \frac{5a}{5} =−+4+ \\ \frac{−5+25 + 5a}{5} = - a + 4 + a [/tex]

3. Combine like terms

[tex] \frac{ - 5a + 25 + 5a}{5} = −+4+ \\ \frac{25}{5} = −+4+[/tex]

4. Cancel terms that are in both the numerator and denominator

[tex] \frac{25}{5} = −+4+ \\ 5 = −+4+[/tex]

5. Combine like terms

5 = - a + 4 + a

5=4

Answer: 5=4.
