Answer:
X = savings, p= pay per hour
X+4p = 86 - - - - (1)
X+6p=104 - - - - - (2)
Re arrange equation (1)
X=86-4p-----(3)
Substitute (3) in (2)
86-4p +6p=104
86+2p=104. (subtract 86 from both side)
2p = 18. (divide by 2 from both side)
Then p =$9
By substitute in equation (1)
X = $50

Answer:
In order to find the value of s, we must isolate the s variable in this equation, so the first step should be subtracting 3 5/6 from both sides of this equation. In order to subtract, we multiply each denominator to get 42, and multiply the numerator by the same amount, and subtract the number from both sides:
s + 3 35/42 = 9 6/42
s = 5 13/42
