Answer:

2x + 15= 33

Step-by-step explanation:

Jerry started doing sit-ups every day. The first day he did 17 sit-ups. Every day after that he did 4 more sit-ups than he had done the previous day. Today Jerry did 73 sit-ups. Write an equation that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day. Let n represent the number of days.

Solve the system of equations algebraically: 2x - y = -1 3x + y = 6

Sindrei [870]

Using substitution method
from the first equ
2x+y=-1
y= -1-2x --------(3)
put equ 3 into equ 2
3x -1-2x=6
3x-2x=6+1
x =7
put x+7 into equ 1
2(7) + y = -1
14 + Y =-1
y= -1-14
y=-15
so
x=7 and y=-15
