Answer:

a = -25

b = [tex]\frac{33}{2}[/tex]

Step-by-step explanation:

Step 1 - Subtract 36 from both sides of the first equation:

a + 36 = 11

a + 36 - 26 = 11 - 36

a = -25

Step 2 - Substitute in the known a value:

a + 2b = 8

-25 + 2b = 8

Step 3 - Add 25 to both sides:

-25 + 2b + 26 = 8 + 25

2b = 33

Step 4 - Divide both sides by 2:

2b ÷ 2 = [tex]\frac{33}{2}[/tex]

b = [tex]\frac{33}{2}[/tex]

Hope this helps!
