8x+30=4x+18
-4x -4x
4x+30=18
-30 -30
4x=-12
4x/4=-12/4
x=-3
Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x
x + 30 = 64 Therefore, x = 64 - 30 x = 34
x2 +7x = 30 x2 +7x - 30 = 0 (x + 10)(x - 3) = 0 Now: x + 10 = 0 or x - 3 = 0 So: x = -10 or x = 3
4x+6x=30 is the same as: 10x=30 so we divide by 10 and get: x=3 (I do not see how this relates to calculus, but O.K.)
x-int. is -5 y-int. is 6
(3,3)
The sum of 18 + 30 is 48.
It does not help you.
-6
18 + 10 + 20 + 30 + 15 + 50= 143
N+18=30. Subtract 18 both sides N=12
45 = 30 + m Subtract 30 from both sides: 15 = m
To solve this one, subtract 50 from 180 and you'll have your answer.
30 - 12 = 18
11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3
v is -15... -15*2 = -30... -30+11= -19.
x = 6 and y = -2
