ANSWER: ⇒ ¹/₃
Solve the equation:
6a - 4 = -2
Rearrange variables to the left side of the equation:
6a = -2 + 4
Calculate the sum or difference:
6a = 2
Divide both sides of the equation by the coefficient of variable:
a = ²/₆
Cross out the common factor:
a = ¹/₃
If jack sells 3 subscriptions in an hour and sue sells 5 subscriptions in an hour they will both earn $18 per hour
26 banana and 14 strawberry
2xB + 2.5xS = 87
B+S=40
Then B=40-S replace B in first equation
2x(40-S)+2.5xS=87
80-2xS+2.5xS=87
-2xS+2.5xS=7
0.5xS=7
S=14
40-14=26=B
The greatest common factor is 6
For this case we have the following system of equations:
To solve, we follow the steps below:
We multiply the second equation by -4:
We add the equations:
Equal signs are added and the same sign is placed.
We look for the value of the variable "x":
Thus, the solution of the system is:
