Answer:
y = 20x + 5
Step-by-step explanation:
X = Y/20 - 1/4
In this type of expression you will first of all find the LCM of the right hand side
x = y - 5/ 20
the next thing to do is to cross multiply
we have,
20x = y - 5
dont forget we are to solve for y in the equation, so to solve for y we have
20x + 5 = y
therefore y will be expressed in terms of x as written below
y = 20x + 5
Let the numbers be x and y
x + y = 100
-
x - y = 26
________
0x + 2y = 74
2y = 74
y = 74/2 = 37
y is actually the less number = 37. The second equation tells y is lesser.
Answer:
- Plan: separate the variable term from the constant term; divide by the coefficient of the variable.
- Steps: add 4 to both sides; collect terms; divide both sides by 3.
Step-by-step explanation:
The first step is to look a the equation to see where the variable is in relation to the equal sign, and whether there are any constants on that same side of the equal sign.
Here, the variable terms are on the left, and there is a constant there, as well. The plan for solving the equation is to eliminate the constant that is on the same side of the equation as the variable, then divide by the coefficient of the variable. To find that coefficient, we need to collect terms. In summary, the plan is to ...
- add 4 to both sides of the equation
- collect terms
- divide by the coefficient of the variable (3)
Executing that plan, the steps are ...
-2x -4 +5x +4 = 8 +4 . . . . add 4
3x = 12 . . . . . . . . . . . . . . . collect terms
x = 4 . . . . . . . . . divide by 3
X<=50.
< is less than
> is greater than
Without him paying the extra fee is <=50
x is pounds.
Now, you have x<=50.
Hope this helped☺☺
