It is like saying, "How much is 8 yams plus 2 yams plus 3 yams?"
Add the numbers: 8+2+3 = 13. The answer is the number of yams.
8y+2y+3y = (8+2+3)y = 13y.
-4(7x-3y-z)-(-6)(9x-z+2)
3y+2z
It is y+3y-2y = 2y simplified
Then 3y+1-2y can be simplified to y+1
To combine the expressions (-4x + 3y + x) and (-2z + 2y), first simplify the first expression by combining like terms: (-4x + x = -3x), so it becomes (-3x + 3y). Now, add the second expression: (-3x + 3y - 2z + 2y). Combining the (y) terms gives you (-3x + 5y - 2z). The final result is (-3x + 5y - 2z).
-4(7x-3y-z)-(-6)(9x-z+2)
3y+2z
5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y
3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8
It is y+3y-2y = 2y simplified
X + 3y - 2y + 3y = X + (3-2+3)y = X + 4y
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
Then 3y+1-2y can be simplified to y+1
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
-3y + y = -2y
To combine the expressions (-4x + 3y + x) and (-2z + 2y), first simplify the first expression by combining like terms: (-4x + x = -3x), so it becomes (-3x + 3y). Now, add the second expression: (-3x + 3y - 2z + 2y). Combining the (y) terms gives you (-3x + 5y - 2z). The final result is (-3x + 5y - 2z).
