how to solve 18x - (8x - 7) + 67
To solve the expression 18x - (8x - 7) + 67, we need to simplify it step by step. Here's how you can go about it:
Step 1: Start by distributing the negative sign inside the parentheses. Multiply -1 with each term inside the parentheses.
18x - 8x + 7 + 67
Step 2: Combine like terms. In this case, we can simplify 18x - 8x to give 10x.
10x + 7 + 67
Step 3: Simplify further by combining the constants. 7 + 67 equals 74.
10x + 74
So the solution to the expression 18x - (8x - 7) + 67 is 10x + 74.
To solve the expression 18x - (8x - 7) + 67 step-by-step, follow these steps:
Step 1: Simplify the expression inside the parentheses.
- Since the sign before the parentheses is a subtraction, distribute the negative sign to every term within the parentheses.
8x - 7 becomes -8x + 7.
- The expression now becomes: 18x - 8x + 7 + 67
Step 2: Combine like terms.
- Combine the x terms, which are 18x and -8x.
18x - 8x = 10x
- The expression now becomes: 10x + 7 + 67
Step 3: Simplify further by combining constants.
- Combine the constant terms, which are 7 and 67.
7 + 67 = 74
- The expression now becomes: 10x + 74
Therefore, the solution to the expression 18x - (8x - 7) + 67 is 10x + 74.
