It is solved when you have it in the form of (x = some number). In this case, you have 7x on one side, which is 7 times x. You need to divide both sides by 7, so you have: 7x / 7 = 7/7.
On the left side, this becomes x. On the right side 7/7 = 1, so x=1 solves the equation. If you 'plug in' x=1 to the original equation, you get 7(1) = 7, or 7 times 1 equals 7, which is true.

Add 3 to 46 then divide by 7.
Solve for x rounding to the nearest 100th 7x equals 12?
7x = 12Divide each side by 7:x = 12/7 = 1.71 (rounded)
Solve 7x 6y equals 126?
Not sure if you mean 7x 6y as in 7*6y=126, where * means "multiplied by" and you must solve for y or if you mean that we must solve for both x and y, but the answer to the part where you are solving 7*6y=126 is 3.
7x plus 7 equals 28 x equals?
7x+7=28x 28x-7x=7 21x=7 x=3
Solve for y 7x plus y equals 4?
7x + y = 4y = 4 - 7x
