When X = 2, we substitute this value into the equation f(x) = 3x-1
3(2)-1 = 6-1=5
f(x)=5
Answer:
x=5
Step-by-step explanation:
10 +3x = 5x
Subtract 3x from each side
10+3x-3x= 5x-3x
10 =2x
Divide each side by 2
10/2 = 2x/2
5 =x
Answer:
64

Answer:
= 40g -24
Step-by-step explanation:
you would multiply everything in the bracket by 8 to expand this
e.g.
(8x5g )+ (8x5 )+ (8 x -2)
= 40g + 40 - 16
now simplify by subtracting the like terms
= 40g -24
