Answer:

a = 1

b = 1

Step-by-step explanation:

I'm using substitution to solve.

So set one equation to equal a variable so, change 2 = a + b to become          a = 2 - b

Then substitute into other equation so:

6 = 4(2 - b) + 2b, and solve for b

6 = 8 - 4b +2b

-2 = -2b

b = 1

Plug back into an equation to solve for a

2 = a + 1, and solve for a

a = 1
