Create an equation from the word problem. 'of' indicates multiplication, 'decreased' indicates subtraction, 'increased' indicates addition. Let's use 'x' for the number.
![\sf\dfrac{7}{10}x-13=\dfrac{3}{10}x+13](https://tex.z-dn.net/?f=%5Csf%5Cdfrac%7B7%7D%7B10%7Dx-13%3D%5Cdfrac%7B3%7D%7B10%7Dx%2B13)
Now solve for 'x'. Subtract 3/10x to both sides:
![\sf\dfrac{4}{10}x-13=13](https://tex.z-dn.net/?f=%5Csf%5Cdfrac%7B4%7D%7B10%7Dx-13%3D13)
Add 13 to both sides:
![\sf\dfrac{4}{10}x=26](https://tex.z-dn.net/?f=%5Csf%5Cdfrac%7B4%7D%7B10%7Dx%3D26)
Divide 4/10 to both sides or multiply by its reciprocal, 10/4:
Answer:
186
Step-by-step explanation:
Divide 4 and 6.0 get 86 add 100 = 86 + 100 = 186
100% right. Kinda confusing ..
A
8p + 4
Meaning we could split it and do 2*4*p +4
Just follow PEMDAS
