Solve the system of equations by substitution. what is the solution for x? . 2x + y = 1. 4x + 2y = −1. x = 0. x = 2. there is no x value as there is no solution..

y=11,x=8

Step-by-step explanation:

2x+y=1

4x+2y=-1

substitution method

y=2x-1

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

4x+4x-2=1

8x-2=1

8x=1

x=8

equation 2

4x+2y=-1

4(8)+3y=-1

32+3y=-1

-33=3y

y=11

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
