Answer:
y=x−3
Step-by-step explanation:
Flip the equation.
4y+7=4x−5
Add -7 to both sides.
4y+7+−7=4x−5+−7
4y=4x−12
Divide both sides by 4.
y=x−3
ik this doesnt make any sense but hope this helps :/
If nine plus 10 is 21 and the square root of the sun is blank
If (55 + x)/2 is to be 67, then 55+x = 2*67, so x = 2*67 - 55 = 79
Answer:
(3, 2), (2, 3)
Step-by-step explanation:
x + y = 5
xy = 6
Solve the first equation for x.
x = 5 - y
Substitute 5 - y for x in the second equation.
xy = 6
(5 - y)y = 6
5y - y² = 6
y² - 5y + 6 = 0
Factor.
(y - 2)(y - 3) = 0
y - 2 = 0 or y - 3 = 0
y = 2 or y = 3
Now substitute 2 for y in the first equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
One solution is x = 3; y = 2, or (3, 2).
Now substitute 3 for y in the first equation and solve for x.
x + y = 5
x + 3 = 5
x = 2
Another solution is x = 2; y = 3, or (3, 2).
Answer: (3, 2), (2, 3)
