Question

Writ an equivalent expression for 7x + 4x + 3 - 1

Answer 1

Answer for this problem is:

11x+2

Answer 2

Answer:

11x +2

Step-by-step explanation:

This question involves combining like terms.

So you need to know that two add 7x and 4x, we add the coefficients (7 and 4) to get 11x. Then for +3 -1, we just simply work this out as 3-1 = 2.

So we now have 11x +2. As 11x and 2 are not 'like terms', we cannot simplify any further.
