Question

A+36=11
a+2b=8
using elimination ​

Answer 1

a = -25

b =
`(33)/(2)`

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 =
`(33)/(2)`

b =
`(33)/(2)`

Hope this helps!

Answer 2

a= -25

b = 16.5
