The best possible first step would be to multiply equation one by 4 and equation by 5 that would eliminate the y and allow you to solve for x.
In essence, 4 × (3x + 5y = 1) eq1
5 × (2x + 4y = -4) eq2
thus giving rise to 12x + 20y = 4 eq1 × 4
10x +20y = -20 eq2 × 5
You can then just subtract one equation from the other
For example, (12x + 20y = 4) - ( 10x +20y = -20 )
12x - 10x + 20y - 20y = 4 - (-20)
2x = 24
x = 12
Answer:
3/4
Step-by-step explanation:
Let the unknown number be x.
Subtract 1/2 from the unknown number: x - 1/2
Multiply the result by 1/2: 1/2(x - 1/2)
You get 1/8: 1/2(x - 1/2) = 1/8
Now we solve the equation for x.
1/2(x - 1/2) = 1/8
Multiply both sides by 2.
2 * 1/2(x - 1/2) = 2 * 1/8
x - 1/2 = 1/4
Multiply both sides by 4
4x - 4 * 1/2 = 4 * 1/4
4x - 2 = 1
Add 2 to both sides.
4x = 3
Divide both sides by 4.
x = 3/4
Answer: The number is 3/4.
