Hayley begins solving this problem by combining like terms. 3x + 5x = 10 which problem begins the same way? a) 5x = 20 b) 3(x + 5) = 20 c) x/4 = 30 d) 3x - 2x = 10

Solution: The given equation is →3 x+ 5 x=10

As you can see in the above equation on left side of equation the two terms are variables and on right side of equation the term is a constant term.Also you can see there is an operation called addition between the two variables on left side of equation.

In option (A), there is only a single term on right as well as left,so this can't be true.

In option (B), there is a constant and variable on left side of equation.So this is also untrue.

In option (C), variable being divided by numerator, so this is also untrue.

Option (D)3 x - 2 x = 10,  is surely correct , because there are two variables on left side of equation and one constant on right side of equation, and there is an operation called subtraction between them .
