Answer:
Solution: { -29/3 , -10/3 }
Step-by-step explanation:
2y = x + 3 ---------> equ 1
5y = x - 7 equ 2
equ 1 - equ s ====> -3y = 10
y = -10/3
Put y = -10/3 in equ 1
2 * (-10/3) = x + 3
-20/3 = x + 3
(-20/3) - 3 = x
(-20/3) - (9/3) = x
(-20 - 9) / 3 =x
x = -29/3
Solution: { -29/3 , -10/3 }
For number three they are all equal
Answer:The short answer would be y=2x+4
Step-by-step explanation:
Here's why standard form is y=mx+b.
Thus, if we solved 2x-y=-4, we would get y+2x+4.
1. 2x-y=-4
2. -y= -2x-4
3. y=2x+4
