Answer:
26/x = 13
x = 2
Step-by-step explanation:
2(x - 4) = 4
2x - 8 = 4
2x = 4 + 8
2x = 12
x = 12/2
x = 6
26/x = 13
Cross product
26 = x * 13
26 = 13x
x = 26/13
x = 2
- 3.8x = -7.4
x = -7.4 / -3.8
x = 1.95
4(x - 1) - 3(x - 2) = -8
4x - 4 - 3x + 6 = -8
x + 2 = -8
x = -8 - 2
x = -10
You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule
ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2)
Or you can put the rule in a graphing calculator and check the points from there
