Question

3. Solve for a

5(a-2) = 2(10+a)

it’s due by midnight and can you also tell me how you got the answer

Answer 1

a = 10

Explanation:

`5(a - 2) = 2(10 + a) \\ \\ 5a - 10= 20 + 2a\\ \\ 5a - 2a= 20 + 10\\ \\ 3a = 30\\ \\ a = (30)/(3) \\ \\ \huge \red{ \boxed{a = 10}}`

Answer 2

a=10

Explanation:

distribute on both sides to get

5a-10=20+2a

add/subtract like terms

5a-2a=3a

20+10=30

so the equation is

3a=30

divide 30 by 3 and you get 10
