Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2). Write a formula for y in terms of x.
The tens digit is 2 more than the units digit. Using the letters x and y, write out the proper equation.
Now solve your two equations simultaneously for x and y.
Answer:
8
Step-by-step explanation:
× 8
= 3
In algebra:
× y = 3
y = 3 ÷
y = 8
The answer is (-4, 5) x= -4 y= 5
Hello :
<span>1.5x - 3y = 6
3y = 1.5x - 6
y = (1.5x - 6)/3</span>
