Question

Simplify by combining like terms: -18 + 3(5x - 2) + 8

Answer 1

Answer:

15x - 16

Step-by-step explanation:

Step 1:  Distribute

-18 + 3(5x - 2) + 8

-18 + (3 * 5x) + (3 * -2) + 8

-18 + 15x + (-6) + 8

-18 + 15x - 6 + 8

Step 2:  Combine like terms

-18 + 15x - 6 + 8

15x - 16

Answer:  15x - 16

Answer 2

Answer:

-16+15x

Step-by-step explanation:

-18 + 3(5x - 2) + 8

When an expression with multiple sign is given, the rule of BODMAS is used. That is Bracket of Division Multiplication Addition and Subtraction. And it will be solved in the order.

-18+15x-6+8

Collect like terms

-18-6+8+15x

-16+15x

The question is an algebraic expression. An algebraic expression is an expression with no equality sign. It can only be solved by collecting the like terms and then simplifying it to its simplest
