Question

find the solution of this sytsem of equations8x-4y=-32 & -3x+4y=-42

Answer 1

Add both equations together, this will eliminate the y variable and you'll just have to solve for x.
Then substitute the value of x back into one of the equations and solve for y.

Answer 2

makes ni sence

Answer 3

First step. Add both equations together:
8x -4y = -32
+(-3x+4y=-42)
-----------------

What do you get?

Answer 4

like add what and what together -32 and -42

Answer 5

All of them:
8x-3x=how many x's
-4y+4y=how many y's
-32-42= what number

Answer 6

X=5 Y=0 AND NUMBERS=10

Answer 7

With the new values your form a new equation.
5x=10
Next step: Solve for x

Answer 8

would it be 5?

Answer 9

No. According to the equation it's a number that multiplied times 5 will give you 10.

Answer 10

2?

Answer 11

Right. Now next step.
Substitute that value in place of the x's in either one of the two original equations.
8x-4y=-32
8(2)-4y=-32
Do the operation, then solve for y.
