To find the equivalent expression, we can simply add the like terms:
(7xy-3xz+yz) + (3xy-5xz+4yz)
Group the like terms together:
(7xy + 3xy) + (-3xz - 5xz) + (yz + 4yz)
Combine the like terms:
10xy - 8xz + 5yz
Therefore, the equivalent expression is 10xy - 8xz + 5yz.
(7xy-3xz+yz) + (3xy-5xz+4yz)
Group the like terms together:
(7xy + 3xy) + (-3xz - 5xz) + (yz + 4yz)
Combine the like terms:
10xy - 8xz + 5yz
Therefore, the equivalent expression is 10xy - 8xz + 5yz.
which expression is equivalent to: -4(2x+3)+5?
-8x+8
-8x-7
-8x+7
14x
-8x+8
-8x-7
-8x+7
14x
To find the equivalent expression, we need to distribute the -4 to each term inside the parentheses and then simplify:
-4(2x+3) + 5
-4 * 2x + -4 * 3 + 5
-8x - 12 + 5
-8x - 7
Therefore, the equivalent expression is -8x - 7.
-4(2x+3) + 5
-4 * 2x + -4 * 3 + 5
-8x - 12 + 5
-8x - 7
Therefore, the equivalent expression is -8x - 7.

To find the equivalent expression, we need to distribute -4 to each term inside the parentheses:
-4(2x+3) + 5
= -4 * 2x + -4 * 3 + 5
= -8x - 12 + 5
Next, we can simplify by combining like terms:
= -8x - 7
Therefore, the equivalent expression is -8x - 7.
-4(2x+3) + 5
= -4 * 2x + -4 * 3 + 5
= -8x - 12 + 5
Next, we can simplify by combining like terms:
= -8x - 7
Therefore, the equivalent expression is -8x - 7.
simply 1/3(9x+15)
To simplify the expression 1/3(9x+15), we need to distribute 1/3 to each term inside the parentheses:
1/3(9x+15)
= 1/3 * 9x + 1/3 * 15
= 3x + 5
Therefore, the simplified expression is 3x + 5.
1/3(9x+15)
= 1/3 * 9x + 1/3 * 15
= 3x + 5
Therefore, the simplified expression is 3x + 5.
10-(x-3)
To simplify the expression 10 - (x - 3), we need to distribute the negative sign to each term inside the parentheses:
10 - (x - 3)
= 10 - x + 3
= 13 - x
Therefore, the simplified expression is 13 - x.
10 - (x - 3)
= 10 - x + 3
= 13 - x
Therefore, the simplified expression is 13 - x.
