Question

8a-2b=12
1a+4b=10
Simaltaneous equation

Answer 1

Step-by-step explanation:

8a - 2b =12_____ (1)

1a + 4b =10______(2)

multiply by 2 in (1) equation

16a - 4b =24_______(3)

now by adding (2) and (3) equation

1a + 4b =10

+16a-4b =24

17a. = 34

a = 34/17

a = 2

now a= 2 put in (2) equation

1 (2) + 4b =10

2 + 4b = 10

4b = 10 -2

4b = 8

b = 8/4

b= 2
