Define a variable and write an equation that can be used to determine the amount of money Tyler and trey have saved. part 2 solve the equation. part 3 how much money has each boy saved
Let
x -----> amount of money Tyler have saved
y -----> amount of money Trey have saved
we have
x=y+27 ------> equation A
x+y=85 -----> equation B
solve the system of equations
substitute equation A in equation B
(y+27)+y=85
solve for y
2y=85-27
2y=58
y=29
Find the value of x
x=y+27
x=29+27
x=56
therefore
amount of money Tyler have saved was $56
amount of money Trey have saved was $29
