Question

Solve the simultaneous equation,5a-2b=14, 2a+2b=14 what is the answer

Answer 1

Answer:

a = 4 and b = 3

Explanation:

The first given equation is:

5a - 2b = 14

This equation can be rewritten as :

2b = 5a - 14 ............> equation I

The second given equation is:

2a + 2b = 14 ...............> equation II

Substitute with equation I in equation II and solve for "a" as follows:

2a + 2b = 14

2a + 5a - 14 = 14

7a = 28

a = 4

Now, substitute with "a" in equation I to get "b" as follows:

2b = 5a - 14

2b = 5(4) - 14

2b = 6

b = 3

Hope this helps :)
