Answer:
The answer to your question is below
Step-by-step explanation:
f(x) = 2x + 5
To solve letter a, just multiply each term of f(x) by 3 and subtract 2.
a) 3f(x) - 2 = 3(2x + 5) - 2
= 6x + 15 - 2
= 6x + 13
To f(x) subtract twice g(x)
b) f(x) - 2g(x) = 2x + 5 - 2(x² - 3x + 2)
= 2x + 5 - 2x² + 6x - 4
= -2x² + 8x + 1
Multiply 5 by each term of f(x) and divide it by g(x)
c)
= 
Answer:
The numbers are 87 and 106
Step-by-step explanation:
x + y = 193
x - y = 19
Add y to both sides of the equation
x = 19 + y
Substitute new value for x into first equation
19 + y + y = 193
Add y's together
19 + 2y = 193
Subtract 19 from both sides of the equation
2y = 174
Divide both sides of the equation by 2
y = 87
193 - 87 = 106
The numbers are 87 and 106
Hope this helps :)
7x-5x=16
2x=16
x=8
so 7*8=56
5*8=40
56:40
56-40=16
