Hey There!
Use the principles of PEMDAS and the distributive property in order to solve this problem.
P- Parentheses
E- Exponent
M- Multiplication
D- Division
A- Addition
S- Subtraction
Let's begin to solve.
7 * -12x = -84x
7 * -3 = -21
10 * 6= 60x
10 * 7= 70
-84x - 21 + 60x + 70
Combine like terms
-84x + 60 = -24x
70 - 21 = 49
Therefore, the answer would be -24x + 49.
