Question

solve 7+ 2 ( a + 1 ) - 3 a = 5 a​

Answer 1

Answer:

a = 3/2

Step-by-step explanation:

7+2(a+1)-3a=5a

》9-a-5a=0

》9-6a= 0

》6a=9

》a= 9/6

● a= 3/2

Answer 2

✒ CORRECT QUESTION :-

Solve 7+ 2 ( a + 1 ) - 3 a = 5 a

★ SOLUTION:-

✦ Reorder the terms:

$\implies \sf \: 7 + 2(1 + a) + -3a = 5a \\ \\ \implies \sf \: 7 + (1 × 2 + a × 2) + -3a = 5a \\ \\ \implies \sf \: 7 + (2 + 2a) + (-3a) = 5a$

So,

${\underline {\bold {\boxed {\sf {\blue{7 + 2a + 2- 3a = 5a }}}}}}$

✒ Now taking variable on L.H.S. and numeric value on R.H.S.

$\implies \sf \: 2a - 3a - 5a = -2 -7 \\ \\ \implies \sf \: -6a = 9 \\ \\ \implies \sf \: a = 3/2$

${\underline {\bold {\boxed {\sf {\pink{∴ a = 3/2 }}}}}}$
