Step-by-step solution

2 steps

Here are the solutions to the problems you've provided:

1. Evaluate 15−4×2+315 - 4 \times 2 + 3

  1. Perform the multiplication.

    15−(4×2)+315 - (4 \times 2) + 3 15−8+315 - 8 + 3

  2. Perform subtraction and addition from left to right.

    (15−8)+3(15 - 8) + 3 7+37 + 3 1010

    The evaluated expression is 10\boxed{10}.

    **2. Solve the simultaneous equations 2m+n=162m + n = 16 and $3m - 2n
