Answer:
Step-by-step explanation:
Le the numbers be x and y
<u>Then we have equations:</u>
<u>As per the first equation:</u>
<u>Substitute in the second equation</u>
- 5x - 2(32 - x) = 195
- 5x + 2x - 64 = 195
- 7x = 195 + 64
- 7x = 259
- x = 259/7
- x = 37
<u>Then finding the value of y</u>

Not 100% sure but hope this helps!
We can do this by following the order of operations procedure. PEMDAS.
= Parentheses Exponent Multiply Division Add Subtract
So in this case we work out the parentheses first , then the multiply:-
5(8 + 7)
= 5 * 15
= 75 (answer)
