2[4(x+y) - 3(6x-15y)]
The order of operations --> PEMDAS
P = operations within Parentheses
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction
First distribute the 4 across the (x+y) and the 3 across the (6x - 15y)
2[4x + 4y -18x + 45y]
Next do the addition and subtraction of like terms within the brackets [ ]
2[4x - 18x + 45y + 4y]
2[-14x + 49y]
Finally, distribute (multiply) the 2 across the terms inside the bracket and you'll have your answer.
