Y=15/(2c+2x)
5x+y=-7 3x+y=15 8=D
15 + n = 24 (subtract 15 from both sides) n = 9
depends what 'a' =
-0.5
Y=15/(2c+2x)
15+b = 23 Subtract 15 from both sides b = 8
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
5x+y=-7 3x+y=15 8=D
In math problems without punctuation such as brackets, the standard convention in to solve from left to right. Therefore, you would solve the problem 15-3 times 4 plus nine like by three actions. 15-3 equals 12; 12 times 4 equals 48; 48 plus 9 equals 57.
(0,7)
15 + n = 24 (subtract 15 from both sides) n = 9
80 = 3y + 2y + 4 + 1 75 = 5y 15 = y y = 15
If: 20x+5y = 15 Then: y = -4x+3
8x+39 = 2x-15 6x = -54 x = -9
