Well the problem 25) it's ez, how can u see* the lines are straight, as well as the columns, as the rows. So if the two lineas are straight that's means, that is a 90 degree angle, therefore all corners have the same formula. like this:
x + 96 = x + 96
-96 -96
__________
x = x - 0
-x -x
__________
-x = 0
True for all x
and the second one its the same, use the both formulas for do this:
26) 20x + 5 = 24x - 1
Answer: x = 3/2
27) 6x = 5x +10
Answer: x = 10
28) x + 109 = x + 89
Answer: No solution
Happy to help you!!☺️
