Answer:
27
Step-by-step explanation:
substitute x = - 3, a = - 5 into the expression
- 4x - 3a
= - 4(- 3) - 3(- 5)
= 12 + 15
= 27
Answer:
x = 16
Step-by-step explanation
Find the diagram attached. You can see from the diagram that both angles are vertically opposite angles and vertically opposite angles are equal.
Hence 2x+13 = 3x-3
Collect like terms
2x-3x = -3-13
-x = -16
Multiply both sides by -1
-1(-x) = -1(-16)
x = 16
Hence the value of x is 16
