Question

a linear equation in one variable given by 3 X + 7 is equal to zero has how many solutions

Answer 1

Solution ... here , is the expression given 3x+7=0

⇒ 3x= −7

⇒ x= −7 / 3 ans

Hence, linear equation 3x+7=0 has only one solution.

Answer 2

HI there !!!

A linear equation can have no solution , 1 solution and 2 solutions , depending on the values which are given.

Here ,

3x + 7 = 0

3x = -7

x = $\frac{-7}{3}$

SO ,
this linear equation in one variable has only one solution
