y=2x+5
y=6x+1

y=2x+5
2x+5=6x+1

y=2x+5
2x-6x=1-5

y=2x+5
-4x=-4 / : (-4)

y=2x+5
x=1

x=1
y=2*1+5

x=1
y=2+5

x=1
y=7

y = 2x+5
y = 6x+1

Just substitute.

y = 2x+5
6x+1 = 2x+5
6x-2x = 5-1
4x = 4
x = 1

Then, insert x = 1 into one of the equation. Let's say I choose number one.
y = 2x+5
y = 2(1) + 5
y = 7
