3x + 2y = 39
-3x -3x
2y = 39-3x
— ———
2 2
y= 19.5 - 3x/2
plug (19.5 - 3x/2) for y
1.5x - 2(19.5 - 3x/2)= 39
x= 17.33333333334
When you multiply, you add the powers and when you divide, you subtract the powers.
1. 2^7
2. 2^6
3. 2^3
4. 2^8
The answer is KL= 11 because x =4
Step-by-step explanation:
a) 2x = 8 x 3
2x = 24
x = 12
b) 3x = 12
x = 4
