bruh- COME. ON. I need the answers o ALL OF THEMMMM- even tho they are ll so easy to solve- TO LAZY. :,/
Huggy wuggy 3. And 5. is not correct!
To find the value of the variable in each equation, you need to isolate the variable on one side of the equation.
Let's go through each equation step by step:
1. 7 + r = 15
To isolate r, subtract 7 from both sides:
r = 15 - 7
r = 8
Therefore, the value of r is 8.
2. 138 = n + 38
To isolate n, subtract 38 from both sides:
138 - 38 = n
100 = n
Therefore, the value of n is 100.
3. 9 = w - 14
To isolate w, add 14 to both sides:
9 + 14 = w
23 = w
Therefore, the value of w is 23.
4. 6.3 = 0.7x
To isolate x, divide both sides by 0.7:
6.3 / 0.7 = x
9 = x
Therefore, the value of x is 9.
Keep in mind that these explanations follow the basic principles of algebraic manipulation. You may encounter more complex equations and will need to apply different methods accordingly.
