In the equation,3x+4= -5x -3 + 15 , what is one of the steps that should be taken to solve for x? combine like terms. add 4 to both sides of the equation. divide both sides of the equation by 5. divide both sides of the equation by 6.

For this case we have the following equation:
 3x + 4 = -5x -3 + 15
 If we want to solve, we must pass the terms that x has on one side of equality and the constant terms on the other side of equality.
 We have then:
 3x + 5x = -4 -3 + 15
 This operation is called:
 Combine like terms.
 Note: then, other steps must be followed to solve the equation.
 
 Combine like terms.
