Question

iii). ( 7a + 2b)
Ans:-​

Answer 1

Simplifying

7a + 2b = 1

Solving

7a + 2b = 1

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-2b' to each side of the equation.

7a + 2b + -2b = 1 + -2b

Combine like terms: 2b + -2b = 0

7a + 0 = 1 + -2b

7a = 1 + -2b

Divide each side by '7'.

a = 0.1428571429 + -0.2857142857b

Simplifying

a = 0.1428571429 + -0.2857142857b
