7 - 9w = - 29
Subtract 7 from both sides
- 9w = - 36
Divide by - 9 on both sides
w = 4
Answer:
(0,5)
(2,1)
(4,-3)
Step-by-step explanation:
so all you have to do is plug in the x value and if the y value comes out to be whatever is matches up with then it is a solution to the equation for example if you plug in 0 to y=-2x+5 then you get 5 and below it says that when x=0 then y=5 which is true so that would be an answer now if you plug in 2 then you get 1 and it says that when x=2 y=9 which is not correct. sorry if this doesnt make sense its so hard to explain virtually
Answer:
k - 2 = 4d - 8
d + 1 = 4d - 8
Step-by-step explanation:
Daniel's age = d
Kevin's age = k
Given that, k = d + 3 -------------- (1)
Two years ago, the age of Daniel = d - 2
Two years ago, the age of Kevin = k - 2
Since, two years ago, Kevin was 4 times as old as
Daniel, k - 2 = 4(d - 2)
Opening the bracket,
k - 2 = 4d - 8
Since the value of k is d + 3 (see (1))
d + 3 - 2 = 4d - 8
d + 1 = 4d - 8
(I am just giving the answer cause I LOVE Linear Equation )
1 + 8 = 4d - d
9 = 3d
9/3 = d
3 = d
Therefore, Daniel's present age is 3 and Kevin's present age = 6
