10 - (3y + 2) = 2 First solve the bracket: 10 - 3y + 2 = 2 Bring all constants to one side: 10 + 2 - 2 = 3y Simplify: 10 = 3y y = 31/3 (3.33333333333)
(3,3)
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
x+3y=2 x= -5 y = 1
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
10y= 6y+5+3y 10y=6+9y y=6
x = 5, y = -1
3y + 8 = 3 -8 -8 3y=-5 (3y)/3=-5/3 y=(-5/3)
3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15
Insufficient information to solve equation, however it can be simplified. Assuming it looks like this 2 (3y+6) The simplified version would be 6y+12
Yes and it works out that x = 3 and y = 4
80 = 3y + 2y + 4 + 1 75 = 5y 15 = y y = 15
