I believe the answer is -1
F(5)= 3.(5)+2=15+2=17
Another example: F(0)=3.(0)+2=0+2=2
You just replace the value in the two sides.
Step-by-step explanation:
PEMDAS
parentheses, exponents, multiplication, division, addition, subtraction.
first multiply:
2×3=6
6+4-5
Now add
6+4=10
Now subtract
10-5=5
5 is the answer

3/5t -4 -7/10t = -2 (as you know 3/5 = 6/10) so
6/10t - 4 - 7/10t = -2
Simplify
-1/10t -4 = -2
add 4 to both sides
-1/10t - 4 + 4 = -2 + 4
-1/10t = 2
multiply -10 to both sides
-1/10t *(-10) = 2 * (-10)
Simplify
t = -20
Answer first one t = -20
