Answer:
5a -4
Step-by-step explanation:
Given
(2a + 3) + (3a - 7) ← remove parenthesis
= 2a + 3 + 3a - 7 ← collect like terms
= (2a + 3a) + (3 - 7)
= 5a + (- 4)
= 5a - 4
Answer:
x is greater than or equal to 19
Your equation states y = 4(-1) + 3
Since the parentheses touch the number 4 which means you multiply, we will start with that first.
4 × -1 or 4(-1) (it means the same thing) would be -4
Now let us combine the equation.
y = -4 + 3
The addition property is included now,
-4 + 3 = -1
Therefore, your answer would be y = -1
Hope this helped! :D
