Question

How many solutions does the system of linear equations 6a + 3b = 12 and 6a - 3b = 12 have?

Answer 1

Answer:

One solution

Step-by-step explanation:

Lets solve it for b

3b= -6a+12

3b= 6a-12

Simplifying

b= -2a+4

b= 2a+4

Both have same slope and intercept hence both lines are going to intersect at one point. So the equations are having one solution.
