i guess i got the answer ...
well..... four times a number b = 4×b = 4b
one more than is +1
and this = 17
now we need to put it all together and forma an equation .... so .. it will be
4b + 1 = 17
4b = 17 - 1
4b = 16
b = 16/4
∴ b = 4
You subtract the second number from the first number.
So 547.25 - 327.875
And you should get the answer 219.375
Part A: 85x, 15y.
Part B: There are 2 terms because he has two jobs only.
Part C the term is 15y
X=6 and x=-8
To solve this, you would treat x-6=0 as one equation, you add 6 to each side to get rid of -6, hence you would get x=6.
Same goes for x+8=0, subtract 8 from each side to get rid of the +8, then you get x=-8
