-13x + 8 = -8x -7
x = 3
1/2(4x - 2) = 19
x = 10
3(x - 3) = -8(2x - 3)
x = 23/19

Tristian needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 4.75 hours and charged him $50 for parts. The total was $643.75. What was the cost of labor, per hour?
2x - 1 = -7x - 37
x = -4
3(-3x - 1) + 5x + 4 = -15
x = 4

Nathaniel wants to ride his bicycle 23.2 miles this week. He has already ridden 4 miles. If he rides for 4 more days, what is the average number of miles he would have to ride each day to meet his goal?
4.8 miles/ 5 miles
2x + x - 4 = 7x + 6 - 8x
x= 5/2
3x - (x + 2) = 4(2x - 1)
x = 1/3
-3(4x - 6) + 7 = 4 (-3x + 7) - 4

Aisha wants to ride her bicycle 18.2 miles this week. She has already ridden 5 miles. If she ride for 4 more days, write and solve an equation which can be used to determine m, the average number of miles she would have to ride each day to meet her goal.
3.3 Miles/ 4 miles
Simplify:
13x - x + y + 13 - 14y - 7 + 20
12x - 13y + 26
-(2x - 6) + 10x = -5x - 2(-7x - 7)
x = - 8
-1/2(-8x - 4) - 9 = 5x + (-x - 7)
-7 = -7
