To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)
3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5
5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11
15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2
5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.

I would combine then solve.
4x+7y=47 /*4 ------>16x + 28y=188
5x-4y=-5 /*7 -------->35x-28y=-35
16x + 28y=188, add this two equations
35x-28y=-35
16x + 28y+35x-28y=188-35
16x +35x=188-35
51x =153m
x=3
5x-4y=-5
5*3-4y=-5
15-4y=-5
4y=15+5
4y=20
y=5
Answer (3,5), B
Answer:
you factories the equation
The answer is A. 1 1/4
You have to subtract 1 3/4 - 1/2 and get 1 1/4
Hope this helps!
