How many solutions does this system have? y=5x-1 y=-3x+7

Mathematics

Vesnalui [34]3 years ago

Answer:

One solution

Step-by-step explanation:

We have the system

y=5x-1\\y=-3x+7

To solve the system, equate both equations and solve for the variable x.

5x-1= -3x+7\\\\5x + 3x = 7 +1\\\\8x = 8\\\\x=1

Now substitute the value of x in any of the two equations and solve for the variable y.

y=5(1)-1

y=4

Finally the system of equations has one solution

Y = 12 because you multiply x by two to get x2, which is 30, and multiply y by two to get 12 - this is wrong, the answer is three, i did the math backwards
