Answer:
I think its B (x-5=13)
Step-by-step explanation:
if its x-5=13
Pedro bought 13 and 5
so 13+5 = 18 (x)
so rearrange the equation to be x-5=13
so imagine x=18 and it would work:
18-5=13
R divided by 14+5. I didn't know where the division sign was. Remember, the work only says to write
an expression, so you don't have to answer it unless it tells you to.
If 21 is added to (+ 21) a number (x) the result (=) is 40 less than (- 40) twice the number (2x)
x + 21 = 2x - 40 Add 40 to both sides
x + 61 = 2x Subtract x from both sides
61 = x Switch the sides to make it easier to read
x = 61
