Answer:

d) x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

622=37x+400

Step 2: Flip the equation.

37x+400=622

Step 3: Subtract 400 from both sides.

37x+400βˆ’400=622βˆ’400

37x=222

Step 4: Divide both sides by 37.

37x/37=222/37

x=6
622 = 400 + 37x
622 - 400 = 400 - 400 + 37x
222 = 37x
222/37 = 37x/37
6 = x
