Question

1. Use the Substitution Method to solve the following system of equations.
x - 4y = 1
2x - 9y = 3

(-1, -3)

(-3, 1)

(3, 1)

(-3, -1)

2. What is the value of the x variable in the solution to the following system of equations?
2x + 3y = 1
3x - 4y = 10

2

-1

1

-2

Answer 1

x=4y+1
2x-9y=3

Answer 2

2(4y+1)-9y=3
solve for y

Answer 3

is it (3,1)

Answer 4

not quite. look at the equation i put up and solve it again

Answer 5

for 1) is (-3,-1) and for 2 ) is 2 that is the right answer

Answer 6

Thank you :)

Answer 7

np

Answer 8

can you help me with some more please

Answer 9

sure

Answer 10

1. What is the value of the y variable in the solution to the following system of equations?
5x + 3y = 7
3x - 5y = -23

-1

1

-4

4

2. For the following system, if you isolated x in the first equation to use the Substitution Method, what expression would you substitute into the second equation?

-x - 2y = -4
3x + y = 12

-2y - 4

2y - 4

2y + 4

-2y + 4

Answer 11

The graph below is represented by which system of inequalities?


-4x + 2y less than or equal to 8
y < -x + 4

-4x + 2y < 8
y less than or equal to -x + 4

-4x + 2y greater than or equal to 8
y > -x + 4

-4x + 2y greater than or equal to 8
y < -x + 4

Answer 12

for ur first one the y is 4 and for 2 the answer i got is x=4 and y=0
