Answer: 4.35 - 5.5 = -1.15 ≈ - (23÷20)
Step-by-step explanation:
4.35 - 5.5= -1.15
The equivalent equation to 4.35 - 5.5 will be,
-1.15 ≈ - (23÷20)
5 times a number plus two is 17
5(x) + 2 = 17
isolate the x, do the opposite of PEMDAS
(Note: What you do to one side you do to the other, because of equal sign)
5x + 2 (-2) = 17 (-2)
5x = 15
5x/5 = 15/5
x = 3
