Question

solve by substitution 5 x + 3 is equals to 3y, 2 x minus y is equals to zero​

Answer 1

Answer:

x=3,y=6

Step-by-step explanation:

5x+3=3y-(1)

2x-y=0-(2)

5x+3=3y

=>5x=3y-3

=>x=3y-3/5

now,substituting x=3y-3/5,We get

2x-y=0-(2)

=>2x=y

=>2×3y-3/5=y

=> 6y-6=5y

=>6y-5y=6

=>y=6

Now,substituting y=6,

2x-y=0

=>2x-6=0

=>2x=6

=>x=3

Hence x=3,y=6.

Answer 2

Step-by-step explanation:

Given -

5x + 3 = 3y

2x - y = 0

To Find -

Value of x and y

Now,

5x - 3y = - 3

y = 2x

Substituting y = 2x on 5x - 3y = - 3,

= 5x - 3(2x) = - 3

= 5x - 6x = - 3

= - x = - 3

• = x = 3

Now,

Substituting x = 3 on y = 2x,

= y = 2(3)

• = y = 6

Hence,

The value of x = 3 and y = 6

Verification -

Substituting the value of x and y on 5x - 3y = - 3

= 5(3) - 3(6) = - 3

= 15 - 18 = - 3

= - 3 = - 3

LHS = RHS

And

Substituting the value of x and y on y = 2x

= (6) = 2(3)

= 6 = 6

LHS = RHS

Hence,
