2(x+4)=16
multiply the bracket by 2
(2)(x)=2x
(2)(4)=8
2x+8=16
move 8 to the other side, sign changes from +8 to -8
2x+8-8=16-8
2x=16-8
2x=8
divide both sides by 2 to get x by itself
2x/2=8/2
Answer:
x=4
I added 8 on both sides to get 12=3x then I divided by 3 on both sides to get x=4
93.725 because you multiply then divide by 2 hope this helps :)
Answer: 14, 15 and 16
Step-by-step explanation:
Let the numbers be a, a+1 and a+2
We are told that the three consecutive integers are such that three times the smallest is 26 more than the largest. This can be formed into an equation as:
(3 × a) = (a+2 + 26)
3a = a + 28
3a - a = 28
2a = 28
a = 28/2
a = 14
The numbers are 14, 15 and 16
Answer:
y = 3
Step-by-step explanation:
It can work well to start by eliminating parentheses.
6(y -1/3) = 4(3y -5)
6y -2 = 12y -20
18 = 6y . . . . . . . . . add 20-6y to both sides
3 = y . . . . . . . . . . . divide by 6
