5a = -5a + 5
Add 5a to each side:
10a = 5
Divide each side by 10:
a = 5/10 = 1/2

If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
5a(a(a-5)+3)
To solve the equation 5a + 5 = 6a - 7, you first want to simplify both sides. Start by combining like terms on each side of the equation. Add 7 to both sides to isolate the variable terms on one side. Then, subtract 5a from both sides to solve for the variable a. The final answer is a = 12.
30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4
