The anwer plus working is 6668/4=151.55
First, you have to simplify the equation:
y+3 = 3(x+5)
y+3=3x+15
So you multiply what’s inside the brackets (x+5) by the factor (3). So 3•x=3x, 3•5=15.
Then you rearrange the equation as necessary to convert it into standard form, which is Ax + By = C
3=4m+ b
-1=3m+b
m=4
plug in to either equation,
3=16+ b
b=-13
Thus, C would be the answer.
M+15=65 could this be the answer you are possibly looking for? if the m is Mai's savings "increased by 15" would simply be adding 15 and it would be equal to 65
