Answer:
x = 27/7 and y = -3/7
Step-by-step explanation:
In order to solve this, we will first solve the first equation for y.
y + 4 = 2/3(x -1)
y + 4 = 2/3x - 2/3
y = 2/3x - 14/3
Now we can plug the value of the equation in for y in the second equation and use it to solve for x.
x + 2y = 3
x + 2(2/3x - 14/3) = 3
x + 4/3x - 18/3 = 9/3
7/3x - 18/3 = 9/3
7/3x = 27/3
x = 27/7
Then we can use this value to find the value of y.
x + 2y = 3
27/7 + 2y = 3
27/7 + 2y = 21/7
2y = -6/7
y = -3/7
Answer:
nope. why should I and it for u?
X = 5.9
In order to solve for x, you'd subtract 31.7 from both sides. This gives you -17.7 = -3x, which you would then divide -3 to both sides. Thus getting x = 5.9 as an answer.
I hope this helps!
Answer:
12
Step-by-step explanation:
6(d+1)−2d=54
Here, we have to find the value of d
multiply (d+1) by 6
6×d + 6×1 - 2 d= 54
6d + 6 - 2d= 54
Now subtract 2 d from 6d
6d- 2d +6= 54
4 d+ 6=54
Now, by using transposition method,
+ 6 will be transferred from L.H.S to -6 to R.H.S
4 d = 54- 6
4d= 48
Now, divide 48 by 4
d= 48÷ 4
d= 12
Hence, the value of d is 12
Hence, the correct answer is 12
