a. 25 – 4y = 6y + 15
b. -5x -4y + 10 = 1
c. 3 (2p – 2) = 5p + 3
d. frac{2x + 7}{5} – frac{x – 3}{2} = frac{3}{10}
Find the solution of each of the following equations!
A. 25-4y=6y+15
-4y-6y=15-25
-10y =-10
y=1
b. -5x-4y+10=1
-5x-4y=1-10
-5x-4y=-9
-5x=-9+4y
-4y=-9+5x
c. 3(2p-2)=5p+3
6p-6=5p+3
6p-5p=3+6
p=9
d. saya kurang tahu
A.
25 – 4y = 6y + 15
25 – 15 = 6y + 4y
10 = 10y
y = 10/10
y= 1
b. -5x -4y + 10 = 1
-5x – 4y = 1 -10
-5x – 4y = -9
5x + 4y = 9….>kalau salah tulis 9x = 9…x=1
c. 3 (2p – 2) = 5p + 3
6p – 6 = 5p + 3
6p-5p = 3 + 6
p = 9
d. (2x + 7) /5 - (x -3) /2 = 3/10…>masing2 kali 10 biar mudah menghitungnya
2(2x+7) – 5(x -3) = 3
4x + 14 – 5x + 15 = 3
-x + 29 = 3
29 -3 = x
x = 26
