a = -2 is the value of linear equation .
What are examples of linear equations?
• An equation with only one variable is referred to as a linear equation in one variable.
• It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value.
• One such linear equation in one variable is 9x + 78 = 18.
Step 1 – Write the equation.
3/a + 2 – 6a/a² – 4 = 1/a – 2
Step 2 – rewrite the equation.
3/a + 2 – 6a/a² – 4 = 1/a – 2
Step 3 – Take the LCM.
3(a- 2) – ( a + 2 )/a² – 2² = 6a/a²-4
Step 4 – Further simplify the above expression
3a – 6 – a – 2/a² – 4 = 6a/a² – 4
Step 5 – Cancel out the denominator of both sides and then further simplify.
2a – 8 = 6a
a = -2
