Miscellaneous
The opposite of multiplying is?
Dividing
3(p+4)
3p+12
a + 5 = 8, find a
a = 3
4x/3 = 8, what is the first step?
multiply by 3
2c-2 = 4c-6, find c
c = 2
A number next to the pronumeral is called?
-2(2x+3)
-4x-6
8 = -8+8a, find a
a = 2
8x/2 = 14, find x
x = 3
2u= 7u-20, find u
u = 4
The number by itself (not with a pronumeral) is called?
constant
5(k+3) = 30, find k
k = 3
-22=14-9x, find x
x = 4
(a+12)/5 = 2, find a
a = -2
10a+32 = 2a, find a
a = -4
What is an example of a false equation?
...
-3(2b-2) = 48, find b
b = -7
22 = 9+5x, find x
x = 13/5 or 2 and 3/5
4 = (p-15)/-3, find p
p = 3
3-j = 4+j, find j
j = -1/2
The process for finding a solution is called?
Solving
2(2p+4) = 2(3p-2), find p
p = 6
When x is doubled, then subtracted from 20 and the result is = 14
x = 3
k is doubled and then 6 is added. This result is halved to obtain -20. What is k?
k = -23
x is increased by 10, this has the safe effect as tripling x and subtracting 6. find x.
x = 8
