Thanks,what abou this one?

Use the Substitution method to solve the system of equations.

x + y = 10
y = x + 8

follow the same principle for the first one and u'll get it

u already have
y = x + 8

Subst. that in the first eqn and just follow up from there

CAn you just help me more like in the first one?PLease!:(

2x+0=18

That is correct. x = 9.
