Question

Jose substitutes a value for y in the equation 5y = 3y + 4

How will Jose know if the value is a solution of the equation?

Answer 1

Jose will know if the value is a solution of the equation if both sides end up equaling the same. For example if the ending result is 5=5 then it is a solution. But if the ending result is 4=5 then it’s not a solution

Answer 2

Explanation:

Equation

5y = 3y + 4

combine like terms 3y becomes negative when moved to the left side being that its positive on the right. 4 has no variable so it stands alone on the right side.

-3y + 5y = 4

After adding a low negative to a high positive number. Turns into 2y.

2y = 4

Divide 2 on both sides to remove the number from the variable on the left.

`(2)/(2)`y =
`(4)/(2)`

2 is canceled on the left side which gives the solution for Y.

y = 2
