Solve for a.<br><br> 7a - 2b = 5a + b<br><br> a = 2b<br> a = 3b<br> a = b<br> a = b
larisa [96]

\\&#10;\text{Consider the equation}\\&#10;\\&#10;7a-2b=5a+b\\&#10;\\&#10;\text{to solve for a, we will first add 2b both sides. so we get}\\&#10;\\&#10;7a-2b+2b=5a+b+2b\\&#10;\\&#10;\Rightarrow 7a=5a+3b\\&#10;\\&#10;\text{now subtract 5a both sides. so we have}\\&#10;\\&#10;7a-5a=3b\\&#10;\\&#10;\Rightarrow 2a=3b\\&#10;\\&#10;\text{divide 2 both sides to get}\\&#10;\\&#10;\Rightarrow a=\frac{3b}{2}

Hence the value of a is: 3b/2
