Question

Use substitution to solve each system of equations.
y=5x+1
4x+y=10

Answer 1

y = 5x+1. ____equ(1)

4x + y = 10. ____equ (2)

substituting equ(1) into equ(2)

4x + y = 10

4x + 5x + 1 = 10

9x = 10 -1

9x = 9

x = 1

x = 1 into equ (1)

y = 5x + 1

y = (5 ×1) + 1

y = 5 + 1

y = 6

I hope this will help.

have a nice day dear :)
