Answer:
Step-by-step explanation:
4x + 3y = 6 -----------------(I)
4x - y =2 ---------------------(II)
Multiply (II) by (-1) and then add
(I) 4x + 3y = 6
II) *(-1) <u> - 4x + y = - 2 </u> {Now add, x will be eliminated}
4y = 4
y= 4/4
y= 1
Plugin y =1 in equation (I)
4x +3*1 = 6
4x + 3 = 6
4x = 6- 3
4x = 3
x = 3/4
Answer:
3 - (n - 1) = 1/2(3n - 4)
Step-by-step explanation:
We want to write three minus the difference of a number and one equals one-half of the difference of three times the same number and four as an equation.
Let the number be n.
The first part is: three minus the difference of a number and one:
3 - (n - 1)
The second part is: one-half of the difference of three times the same number and four:
1/2(3n - 4)
Now, let us equate the first and second parts:
3 - (n - 1) = 1/2(3n - 4)
PS: I really do not understand the options
Step-by-step explanation:
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. ... After it has been transferred, energy is always designated according to its nature.
90 + 3 + 4 = 97
Your answer is 97.
