Question

solve 3x-5y-4=0 and 9x-2y-7=0 by elimination method​

Answer 1

Answer:

3x-5y-4=0

Let's solve for x.

3x−5y−4=0

Step 1: Add 4 to both sides.

3x−5y−4+4=0+4

3x−5y=4

Step 2: Add 5y to both sides.

3x−5y+5y=4+5y

3x=5y+4

Step 3: Divide both sides by 3.

3x /3  =  5y+4 /3

x=  5 /3y+ 4 /3

Let's solve for y.

3x−5y−4=0

Step 1: Add 4 to both sides.

3x−5y−4+4=0+4

3x−5y=4

Step 2: Add -3x to both sides.

3x−5y+−3x=4+−3x

−5y=−3x+4

Step 3: Divide both sides by -5.

−5y /−5=−3x+4/ −5

y= 3 /5 x+ −4/ 5

So x =
