Ijust need with three, four, and seven. solve the system of linear equations, and determine if the equation has one solution, infinitely many solutions, or no solution. , explain how you’ve gotten your answer. you so much to whoever takes the time to me out!

3. If and , then

Then

(only one solution)

4. If , then . So we're told that but this is impossible, because that would that for any , we have -5 = -2. This is false, so this system has no solution.

7. "y is 6 less than 3 times x" means . "x is 2 more than one-third of y" means . Solving the second equation for gives , which would mean . But for the same reason as in (4), there is no solution. For any value of , this equation gives the false conclusion that -6 = -2.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
