Answer:
(- 
, 
)
Step-by-step explanation:
Given the2 equations
6 - 2x = y → (1)
14 + 3x = y → (2)
Substitute y = 14 + 3x into (1)
6 - 2x = 14 + 3x ( subtract 3x from both sides )
6 - 5x = 14 ( subtract 6 from both sides )
- 5x = 8 ( divide both sides by - 5 )
x = -
Substitute x = - into either of the 2 equations for the corresponding value of y
Substituting into (1)
y = 6 - 2(- ) = 
+ 
=
solution is ( - , )
Answer:
x = 2±3sqrt(3)
Step-by-step explanation:
(x-2)^2/3=9
Multiply each side by 3
(x-2)^2/3 *3=9*3
(x-2)^2=27
Take the square root of each side
sqrt( (x-2)^2)=±sqrt(27)
x-2 = ±3sqrt(3)
Add 2 to each side
x = 2±3sqrt(3)
16dividedby3 which is 5 and 1 third or 5 remainder 1
Answer: let get started
Step-by-step explanation: the sum of two-thirds of a number and eight is equal to the difference of seven-thirds of the same number and two
Answer: solve the expression by applying BODMAS, then multiply 8 by 2
Step-by-step explanation:
The first operation is to apply BODMAS, then solve the expression in the bracket
3,500÷(34+8×2)−4
3,500÷ (34 + 10) -4
3500 ÷ 44 - 4
3500 ÷ 40
87.5
I hope this helps.
