Simplify, simplify, simplify for problems like this. Add 6x to both sides to get 10x - 8 = 12. Then add 8 to both sides, so 10x = 20. Now divide by 10, and you get x = 2
Answer:
145⁰
Step-by-step explanation:
180 minus 73⁰ plus 62⁰
which is 180 minus 135
145⁰
-16 + 5n = -7(-6 + 8n) + 3 Given
-16 + 5n = 42 - 56n + 3 Distribute
-16 + 5n = 45 - 56n Collect like terms
61n = 61 Add 56n to the left side and add 16 to the right side
n = 1 Divide 61 from both sides
The answer is n = 1. Remember that when you have a number beside two or more numbers in parentheses, you have to distribute, or multiply the number outside the parentheses by each number inside the parentheses.
Hope this helps!
