Question

Solve: y = 5x – 7 and y = 5x + 1 by substitution method.

Answer 1

HEY MATE!!!


HERE IS YOUR SOLUTION

Y = 5X - 7....(1)
Y = 5X + 1....(2).

SUBSTITUTE EQ(1) IN EQ(2).

5X - 7 = 5X + 1

0 = 8

OR WE CAN SAY THAT...

NOT DEFINED EQUATION

Answer 2

Y=5x-7-(i)

So, y=5x+1

5x-7=5x+1 ( substituting the value of y from(i))

Hope this helps
