Question

please do this sum now please and send me now simultaneous linear equation by eliminating method ​

Answer 1

Answer:

i)-3/4y-7

ii)-5/6y-13

Step-by-step explanation:

i)Let's solve for x.

3

x

+4y=7

Step 1: Multiply both sides by x.

4xy+3=7x

Step 2: Add -7x to both sides.

4xy+3+−7x=7x+−7x

4xy−7x+3=0

Step 3: Add -3 to both sides.

4xy−7x+3+−3=0+−3

4xy−7x=−3

Step 4: Factor out variable x.

x(4y−7)=−3

Step 5: Divide both sides by 4y-7.

x(4y−7)

4y−7

=

−3

4y−7

x=

−3

4y−7

Answer:

x=

−3

4y−7

ii)Let's solve for x.

5

x

+6y=13

Step 1: Multiply both sides by x.

6xy+5=13x

Step 2: Add -13x to both sides.

6xy+5+−13x=13x+−13x

6xy−13x+5=0

Step 3: Add -5 to both sides.

6xy−13x+5+−5=0+−5

6xy−13x=−5

Step 4: Factor out variable x.

x(6y−13)=−5

Step 5: Divide both sides by 6y-13.

x(6y−13)

6y−13

=

−5

6y−13

x=

−5

6y−13

Answer:

x=

−5

6y−13

Answer 2

Answer:

3/x +4. =7

5/x +6 =13

x = 1/5 ∧ y = -2

Hope you are doing well and I wish u good
