3y = 5x
y = x + 2
3y = 5x
3(x + 2) = 5x
3x + 6 = 5x
3x - 3x + 6 = 5x - 3x
6 = 2x
6/2 = 2x/2
3 = x
y = x + 2 = 3 + 2 = 5
Thus, the solution of the set is (3, 5)
Check:
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
The solution of 4x plus 3y -9 and x -3 is; 5x+3y-3.
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
