Answer:
a) (-1/2,3/2)
Step-by-step explanation:
-3x = x + 2
4x + 2 = 0
4x = -2
x = -1/2
y = -3(-1/2) = 3/2

Answer: 13 + x = 50
Step-by-step explanation: the sum is 50 , 13 is provided , julie’s age is the variable
The value of (26 - 7) and (5 - 24) when they're multiplied will be -399.
<h3>How to multiply the values?</h3>
From the information given, we are told to multiply (26 - 7) and (5 - 24). This goes thus:
= (26 - 7) × (5 - 24)
= 21 × -19
= -399
In this case, value of (26 - 7) and (5 - 24) when they're multiplied will be -399.
