Question

Solve the following equations and check the results : 2 - 3a + 7 = 8a + 3 - a​

Answer 1

Step-by-step explanation:

2-3a+7=8a+3-a

2+7-3=8a+3a-a

9-3 =11a-a

6 =10a

a=3/5

checking: 2-3(3/5)+7 = 8(3/5) +3 -3/5

9-9/5 = 24/5 +3 - 3/5

45-9/5 = 21/5 +3

36/5 = 21+15/5

36/5 = 36/5

Answer 2

$\ \: \red{answer}$

$2 - 3a + 7 = 8a + 3 - a \\ = > - 3a - 8a + a = 3 - 2 - 7 \\ = > - 12a = - 6 \\ = > a = \frac{ - 6}{ - 12} \\ = > a = \frac{1}{2}$
