you have -8 and twelve you equation is x -12 = -8 so we just have to flip the equation around to make it x = 12 -8 which is easy . You just have to make sure you don't get mixed up while flipping the signs.
Linear Equation: 15m+10=w 15 pages written for every month for 5 months plus the 10 pages she has already written is equal to the total number of pages written in 5 months. m= number months written. In this case, it is 5 months. w= number of pages written in 5 months 15(5)+10=w 75+10=w 85 pages written=w Carla will have written 85 pages in 5 months.
Well -5/8 as a decimal would be -0.625. So, the order would be -0.615 -0.62(0) and then -5/8 (or -0.625). You could easily search up 5/8 as a decimal :)
