Question

i need help

Answer 1

Yes, but what is the problem??

Answer 2

4x+3y=-1
3x+y=-3
determine which am i supposed to use graphing substition or elimantion explain

Answer 3

Use can use substitution here..

From Second Equation, just find the value of y i.e y = -3 - 3x..

Substitute this value in first equation and find y and then find x..

Able in getting what I am saying or not??

Answer 4

yes thanks

Answer 5

Welcome dear...

Answer 6

i have two more
If you wanted to eliminate the y variable by adding the two equations in the following system, what could be your first step?

5x − 6y = 6
x − y = -12

What is the value of the x variable in the solution to the following system of equations?

4x − 3y = 3
5x − 4y = 3

Answer 7

In first equation to eliminate y by adding is to multiply the Second equation by -6 and then add the two equations...

Answer 8

k

Answer 9

In second equation:
multiply 1eq by 5 and 2eq by 4

so,

20x - 15y = 15
20x - 16y = 12

Subtract them:
y = 3

and x = 3..

S0, the value of x = 3..
