Question

How can you solve linear equations and inequalities in one variable, with equations and co-effecients represented with letters?

Answer 1

Suppose,
ax+3=9
Where x=variable and a=coefficient,

Then,
Subtracting 3 from both sides,

ax+3-3=9-3
or, ax=6

Again dividing both sides by co-efficient a

x=6/a
