X = books were sold on Saturday.
Because 2 more books were sold on Sunday than on Saturday, therefore
(x + 2) books were sold on Sunday.
The total number of books sold over the weekend (Saturday and Sunday) is
x + (x+2)
= x + x + 2
= 2x + 2
Answer: 2x + 2
Answer:30=-34
Step-by-step explanation:
First you distribute so 2×X is 2X
2×8 is 16 then you do the other side but you put a one in front of the- so it goes 1 times 3x is 3x and you turn the minus into a plus sign and turn the positive 34 into a negative 34 so -34× 1 is -34 then write that out to look like 14-2X+16= 5X -3X + -34 then you add or subtract the commons which is 14+16= 30 and 5X-3X=2X so now your equation is 30-2x=2X+(-34) then you want to get your X on the same side so you subtract 2X from the right side and the left side then your left 30=-34
Answer:
x = 1
z = 1/2
Step-by-step explanation:

z = 1/2
x = 2z
x = 2(1/2)
x = 1
