Sagot :
Beacause 20-8 is 16 and 2x means that x is multiplied to two which resukted to 16 so 16/2 is 8
so basically it is (2*8)+8= 20
Answer:
x = 8
Step-by-step explanation:
2x+8=20
2x = 20 - 8 [transpose "8" to the right with its similar term]
2x = 16 [solve the right side]
[tex]\frac{2x}{2}[/tex] = [tex]\frac{16}{2}[/tex] [divide both sides by "2" to elimate "2" and find "x"]
x = 8
