Question

Solve the system by elimination method. 0.5x=-2.0+y , -4/3x+y=-29/3

Answer 1

Let's organize the system.
{0.5x-y=-2
{-4/3x+y=-29/3
Let's multiply the second equation by 3 and the first by 2.
{x-2y=-4
{-4x+3y=-29
Now we eliminate x by multiplying the first equation by 4.
{4x-8y=-16
{-4x+3y=-29
We add them.
-5y=-45.
y=9.
so that means x-2(9)=-4.
14-18=-4.
So x=14.
The answer is (14,9).
