Answer:
15x - 4
Step-by-step explanation:
Add both of the equations together.
f(x) + g(x)
(3x + 10x) + (2x -4)
Then, combine like terms
3x + 2x + 10x = 15x
15x - 4
STEP
1
:
Pulling out like terms
Pull out like factors :
32 - 2x = -2 • (x - 16)
STEP
2
:
Equations which are never true:
2.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : x-16 = 0
Add 16 to both sides of the equation :
x = 16
Answer:
12
Step-by-step explanation:
3x + y = 6
Multiply both sides by 2
6x + 2y = 12
At first he had 72 then he gave 27 to his neighbor ( 27 subtract 72 = 45) and then he gave 15 to his brother ( 45 subtract 15 = 30)
he had 30 tomatoes left.
