63. The ratio 63:9 is equal to 21:3 because 3x3 is 9 and 21x3 is 63
Simplifying
a + 5 = -5a + 5
Reorder the terms:
5 + a = -5a + 5
Reorder the terms:
5 + a = 5 + -5a
Add '-5' to each side of the equation.
5 + -5 + a = 5 + -5 + -5a
Combine like terms: 5 + -5 = 0
0 + a = 5 + -5 + -5a
a = 5 + -5 + -5a
Combine like terms: 5 + -5 = 0
a = 0 + -5a
a = -5a
Solving
a = -5a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '5a' to each side of the equation.
a + 5a = -5a + 5a
Combine like terms: a + 5a = 6a
6a = -5a + 5a
Combine like terms: -5a + 5a = 0
6a = 0
Divide each side by '6'.
a = 0
Simplifying
a = 0
We can remove parenthesis if we change the sign of all terms in the second parenthesis (because we're subtracting it).
So, we have
And now we simply have to aggregate like terms:
