The sum of (8y - 14y) is calculated by combining the like terms. This results in (-6y). Therefore, the final answer is (-6y).
8y+6y is 14y
2y+8y = 10y
Solving the given quadratic equation y = -5/2 or y = 3/4
If: 8y-2 = 3-2y Then: 8y+2y = 3+2 So: 10y = 5 Therefore: y = 5/10 or as a 1/2 in its simplest form
5y - 14y = -9y
8y+6y is 14y
Oh, dude, math time! So, you've got 8y + 4x + 6y. Just like mixing different sodas at the fountain, you can combine like terms here. So, that gives you 14y + 4x. Ta-da! Math magic.
If you mean 8y^2 +14y = 15 then the value of y is -5/2 or 3/4
2y+8y = 10y
Solving the given quadratic equation y = -5/2 or y = 3/4
If: 8y-2 = 3-2y Then: 8y+2y = 3+2 So: 10y = 5 Therefore: y = 5/10 or as a 1/2 in its simplest form
5y - 14y = -9y
The perimeter of a rectangle is the sum of the four sides.
If: 14y = 98 Then: y = 7
The perimeter of a triangle is the sum of the lengths of the three sides.If the three expressions in the question are in fact the lengths of thethree sides, then the perimeter is their sum.(7x + 9w) + (2x + 8y) + (2y + 5w) = 9x + 10y + 14w
If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16
14y minus 6y means "14 times a number, minus 6 times the same number". If you have 14 things and you take away 6 things, you are left with 8 things. So, 8 times a number equals 48. 8 times what number gets you 48? Since you are already in Algebra I, you know 8 times 6 gets you 48, so the number (y) is 6. The formal Algebra I approach is to combine like terms, then divide. 14y - 6y = 48 (Subtract 6y from 14 y. (14y - 6y = 8y, and the y does not go away) 8y = 48 (Now divide both sides by 8 to get the y all by itself) 8/8y = 48/8 (8/8 is 1, and 48/8 is 6, so 1y = 6. You can lose the 1 because one thing is the thing itself.) y = 6 Does that help? There are many ways to solve this problem, but Algebra I is teaching the proper steps for solving one, two and three step equations. Stick with it.
