Answer 2

Solution

Given :-

• 8x + 5y = 7__________(1)
• x + y = 4 __________(2)

Find :-

• Value of x & y by Elimination Method

Explanation

Multiply by 5 in equ(2)

• 5x + 5y = 20 ___________(3)

Subtract equ(2) & equ(3) (Eliminate y)

↪ 8x - 5x = 7 - 20

↪3x = -17

↪ x = -17/3

Keep Value of x in equ(3)

↪5 × -17/3 + 5y = 20

↪5y = 20 + 85/3

↪5y = (60+85)/3

↪y = 145/(3×5)

↪y = 29/3

Hence

• Value of x = -17/3
• Value of y = 29/3
