Question

Solve using the substitution method. Show your work. If the system has no solution or an infinite number of solutions, state this.
10x – 4 = 2y
2y – 10x = 2

Answer 1

10x – 4 = 2y ----- (I) rearrange it to get
2y + 4
x = ---------
10

Now substitute it in (II)

2y – 10x = 2 ----- (II)

and solve. You will get value of y.

Substitute that value of y in (I) and get value of x.
