Question

5(a+2)-3(a-1)=3
solve the equation pls​

Answer 1

Step-by-step explanation:

Your question:

$5(a + 2) - 3(a - 1) = 3$

Your answer:

$5a + 10 - 3 a + 3 = 3$

[ use distributive property for the expressions inside the Parentheses]

$= 5a - 3a = 3 - 3 - 10$

[ let the variables be in the LHS and the numerals be in the RHS]

$2a = 3 - 13$

[ just do the mathematical functions ]

$2a = - 10$

[ now let's divide to get your final answer]

$a = \frac{10}{2}$

your final answer:

$5$

Answer 2

$5(a + 2) - 3(a - 1) = 3 \\ \\ 5 \times a + 5 \times 2 - 3 \times a + 3 \times 1 = 3 \\ \\ 5a - 3a \: + 10 + 3 = 3 \\ \\ 2a + 13 = 3 \\ \\ 2a = 3 - 13 \\ \\ 2a = - 10 \\ \\ a = \frac{ - 10}{2} \\ \\ a = - 5$
