Solve the system of equations by substitution. What is the solution for x?

Mathematics
1 answer:
Nostrana [21]3 years ago

Answer:

There is no x value, as there is no solution

Step-by-step explanation:

we have

2x+y=1

Isolate the variable y

y=-2x+1 -----> equation A

4x+2y=-1 ---> equation B

Solve the system of equations by substitution

Substitute the equation A in the equation B and solve for x

4x+2(-2x+1)=-1

4x-4x+2=-1

2=-1 ------> is not true

therefore

The system has no solution

Equation A and equation B are parallel lines with different y-intercepts

nadya68 [22]

X/6 = 15/18

Cross multiply:


18x = 15 times 6

18x = 90

Divide both sides by 18

X = 5


5/6 = 15/18
