Question

Solve the simultaneous equations

3a+2b+1

a+2b=5

a=

b=

Answer 1

Answer: a=-2, b=7/2

Explanation:

To solve for a and b, we can use the elimination method for these system of equations.

3a+2b=1

a+2b=5

Since there is a 2b in both equations, we can subtrac the 2 equations.

2a=-4

a=-2

Now that we have found a, we can plug it into ay of the equations to find b.

-2+2b=5

2b=7

b=7/2
