Question

Please help me fastt with a picture i dont know its our homework

Answer 1

• 2x+y=11,
• 2x=11-y
• x=11-y÷2

• x+3y=8
• 11-y÷2+3y=8
• [11-y+3y×2]÷2=8
• [11-y+6y]÷2=8
• [11+5y]÷2=8
• 11+5y=8×2
• 11+5y=16
• 5y=16-11
• 5y=5
• y=5÷5
• y=1

• so put value of y in any equation
• x+3y=8
• x+3×1=8
• x=8-3
• x=5
