Question

3х + 4y = 18 ; 4x Зу = 17​

Answer 1

Answer:

x = 2 and y = 3

Step-by-step explanation:

• 3х + 4y = 18 and  4x + Зу = 17
• in first equation, 3x + 4y = 18
• x = (18 - 4y)/3
• by putting x value in equation 2 we get,
• 4(18 - 4y)/3 + 3y = 17
• (72 - 16y)/3 + 3y = 17
• 72 - 16y + 9y = 51
• -7y = -21
• y = 3  
• and x = 2(Ans.)
