Jlenok [28]

Answer:

95k

Step-by-step explanation:

Given :

15 words or less = 50k

ozzi

Answer: (2, -3)

The solution of the equation   4x+y=5   and 3x+y=3 be (2 , -3) .

Step-by-step explanation:

As given the equations are .

4x+y=5

3x+y=3

Subtracted 3x+y=3 from 4x+y=5  .

Thus

4x - 3x + y - y = 5 - 3

x = 2

Put in the equation 4x+y=5  .

4 × 2 + y = 5

8 + y = 5

y = -8 + 5

y = -3

Therefore the solution of the equation   4x+y=5   and 3x+y=3 be (2 , -3) .
