Question

Solve the given simultaneous equations : x-y = 4, x+ y = 10 and hence find value of p when y = 3x - p

Answer 1

Step-by-step explanation:

x-y=4....eq.1

x+y=10....eq.2

Adding eq.1 and 2

2x=14

x=7

Putting x=7 in eq.1

7-y=4

y= 3

y=3x-p

3=3×7-p

3=21-p

p=21-3

p=18

Answer 2

Step-by-step explanation:

• (X+Y) + ( X-Y) =4+10
• 2X=14
• X=7
• 7-Y=4
• Y=3
• Y=3X-P
• 3=3×7-P
• P=18
