Question

2x+3=4 and 3x-5y=6 on substitution method

Answer 1

Hey mate here is your answer

STEP BY STEP EXPLAINATION

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

3 y - 5 y= 6 -------2

Taking equation 1

2x+ 3 = 4

2x = 4- 3

x= 1 /2 --------3

Putting the value of x in equation 2

3x - 5y = 6

3 × 1/ 2- 5 y = 6

3/ 2 _ 5 y = 6

3 _ 10 y = 6

----------------

2

3 - 10 y = 12

10 y = 12 - 3

10 y = 9

y = 9 / 10

y = 0.9

Answer 2

Step-by-step explanation:

2x+3=4

2x=4-3

x=1/2

3x-5y=6

putting x=1/2 we get...

3(1/2)-5y=6

=3/2-5y=6

=-5y=6-3/2

=-5y=9/2

y=-9/10
