Answer :
Answer:
a = - c
Step-by-step explanation:
2a - 2c = 4a
- 4a - 4a
- 2a - 2c = 0
+ 2c + 2c
- 2a = 2c
/-2 /-2
a = - c
Answer:
[tex]\boxed {a = -c}[/tex]
Step-by-step explanation:
Solve for the value of [tex]a[/tex]:
[tex]2a - 2c = 4a[/tex]
-Take [tex]4a[/tex] and subtract it from [tex]2a[/tex]:
[tex]2a - 2c - 4a = 4a - 4a[/tex]
[tex]-2a - 2c = 0[/tex]
-Add both sides by [tex]2c[/tex]:
[tex]-2a - 2c + 2c = + 2c[/tex]
[tex]-2a = 2c[/tex]
-Divide both sides by [tex]-2[/tex] and dividing [tex]-2[/tex] undoes the multiplication by [tex]-2[/tex]:
[tex]\frac{-2a}{-2} = \frac{-2c}{-2}[/tex]
[tex]\boxed {a = -c}[/tex]
Therefore, the value of [tex]a[/tex] is [tex]-c[/tex].
