Question

if 4x+3y=5 and 3x+4y=3 then what is the value of x_y?​

Answer 1

Answer:

x and y value =1

Step-by-step explanation:

4x+3y=5

5=4x-3y=1xy

=ans= 1

3x+4y=3

3=4-3=1

=and =1

Answer 2

Answer:

y = -3/7 ≅ -0.42

x = 11/7 ≅ 1.57

Step-by-step explanation:

1. 4x+3y=5 ⇒ -12x - 9y = -15
2. 3x+4y=3 ⇒ 12x + 16y = 12
3. Based on 1 , 2 we conclude⇒ 16y - 9y = 12 - 15 ⇒ 7y = -3 ⇒ y = -3/7
4. Based on 1 , 3 we conclude⇒ 4x + 3(-3/7) = 5 ⇒ x = 11/7 ⇒ x ≅ 1.57
