a = 3b
a = b
a = b

Answer 1

Answer: C that is: a=3/2 b

Step-by-step explanation: edge and if it is wrong sorry its all i got

Answer 2

`\\ \text{Consider the equation}\\ \\ 7a-2b=5a+b\\ \\ \text{to solve for a, we will first add 2b both sides. so we get}\\ \\ 7a-2b+2b=5a+b+2b\\ \\ \Rightarrow 7a=5a+3b\\ \\ \text{now subtract 5a both sides. so we have}\\ \\ 7a-5a=3b\\ \\ \Rightarrow 2a=3b\\ \\ \text{divide 2 both sides to get}\\ \\ \Rightarrow a=(3b)/(2)`

Hence the value of a is: 3b/2
