Find the solution for the system of linear equations by graphing: y=x
Y=2x -4

x and y = 4

Step-by-step explanation:

Since y=x --->         x=2x-4

                              -x  -x

0=x-4            

+4   +4  > Therefore, x= 4 and y= y

If you could graph both lines you would find they intersect at (4,4)

(4,4)

Step-by-step explanation:

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

$12. that is my answer.
