10 more than y
-10
Y - 12 < -10 Add 12 to both sides: Y < 2
It is: y+16+7 = 10 and the value of y is -13
Add: 5x - y + x + y + 8 + 10 ie 6x = 18 so x = 3 and y = 7
15-y/4>10 15-10>y/4 [add y/4-10 to both sides] 5>y/4 [simplify lhs] 20>y [multiply by 4] y<20 [move y to lhs]

X + Y = 18 X - Y = 10 add 2X = 28 X = 14 Y = 4
What is the product of y and 10
X - Y = 10 X + Y = 4 -------------------+ ( add them ) 2X = 14 X = 7 ----------find Y in one of the equations; top looks good 7 - Y = 10 - Y = 3 Y = - 3 ---------------check both equations for consistency 7 - (- 3) = 10 7 + 3 = 10 10 = 10 ------------checks in top 7 + (- 3) = 4 7 - 3 = 4 4 = 4 ------------checks and is consistent (7, - 3) ( the answer )
It is: y^2 -13y +12 = (y-1)(y-12) when factored
