Answer:
3x2y + 3xy (cannot be added)
3x2y + (–12x2y) = -9x2y
3x2y + 2x2y2 (cannot be added)
3x2y + 7xy2 (cannot be added)
3x2y + (–10x2) (cannot be added)
3x2y + 4x2y = 7x2y
3x2y + 3x3 (cannot be added)
Step-by-step explanation:
Adding and subtracting a monomial requires having the same variables. No matter how big or small their coefficient is, if their variables do not match, they cannot be added or subtracted. The crucial part in adding or subtracting monomials is their sign. If the signs are the same, retain the sign. If the signs are different, subtract and keep the sign of the larger number.
(2n - 14)/2 = n - 7....multiply both sides by 2
2n - 14 = 2(n-7)
2n - 14 = 2n - 14
2n - 2n = 14 - 14
0 = 0
this equation will have infinite solutions
Answer:
Step-by-step explanation:
Simplifying
9x + -5 = 10x + -9
Reorder the terms:
-5 + 9x = 10x + -9
Reorder the terms:
-5 + 9x = -9 + 10x
Solving
-5 + 9x = -9 + 10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10x' to each side of the equation.
-5 + 9x + -10x = -9 + 10x + -10x
Combine like terms: 9x + -10x = -1x
-5 + -1x = -9 + 10x + -10x
Combine like terms: 10x + -10x = 0
-5 + -1x = -9 + 0
-5 + -1x = -9
Add '5' to each side of the equation.
-5 + 5 + -1x = -9 + 5
Combine like terms: -5 + 5 = 0
0 + -1x = -9 + 5
-1x = -9 + 5
Combine like terms: -9 + 5 = -4
-1x = -4
Divide each side by '-1'.
x = 4
Simplifying
x = 4
Answer:
The change division should put the unit to be dispensed with as an afterthought inverse of where it happens in the first inquiry.
540 inches * (1 yard/36 inches)
The inches best and base drop, abandoning you with the outcome in yards.
