The first thing you want to do is combine like terms
4 + 5x = 12x -10
and make x on one side alone
14 = 7x
divide by 7 to make x alone
2 = x
The answer is 2
4-(22÷ -11+11)
4-(-2+11)
4-9
-5
Answer:

Step-by-step explanation:
If the speed is constant for 5 machines and produces x amount of toys we know that rate is defined as a constant per time:
Here the machines are constant and the rate is x toys per hour:
If 5 machines make x per hour:
Rate is x/1 hour
The the ratio of 8/5 is 1.6. Therefore for 8 machines the rate is 1.6 times more per hour than for5 machines. Therefore we can write an expression as:
Rate for 5 machines is x and for 8 machines is y:

Answer:
(0,1)
Step-by-step explanation:
The solution to a system of equations is where the two lines intersect. Algebraically, you could solve this by setting the equations equal to each other.
