If 10x=40 then what is x

X is 4.

To get x alone you divide its coefficent.

10 Is the coefficent.

x = 40/10

x = 4

4 hope this helps have a nice day please give me brainliest:)

Step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer is because 4×10=40

and 98×4= is 392

40,392
