6x+y=12
3y+2x=20
To solve this system of linear equations using the elimination method, follow these steps:
- Step 1: Align the equations for elimination. These equations are already simple, but you could multiply the first equation by 3 to align coefficients for y.
- Step 2: Multiply the first equation by 3 to facilitate elimination of y:
3(6x+y)=3×12
Thus, we get:
18x+3y=36.
- Step 3: Rewrite and subtract the second equation from this new equation:
18x+3y−(3y+2x)=36−20,
This simplifies to:
16x=16.
- Step 4: Solve for x:
x=1616=1.
- Step 5: Substitute x=1 back into the first original equation to find y:
6(1)+y=12,
6+y=12,
y=12−6,
y=6.
Therefore, the solution to the system of equations is x=1,y=6.
