Answer:
x=1 or x=9
Step-by-step explanation:
make x the subject of the formula by correcting the right terms and then divid both sides by 2
<span>An equation that is satisfied for every value of the variable for which both sides are defined is called an identity.
For example:
Given the equation
3x + 4 = x + 2(x + 2)
Notice that for any value of x you use, the equation is true.
Thus, this type of equation is called an identity.

Answer:
y = 7x - 5
Step-by-step explanation:
y=mx+b Where m is the slope and b is the y-intercept
Answer:
(-2,-5)
Step-by-step explanation:
y = 2x-1
3x-y = -1
We can use substitution
3x - (2x-1) = -1
Distribute the minus sign
3x -2x+1 = -1
x +1 =-1
Subtract 1 from each side
x+1-1 = -1-1
x=-2
Now we need to find y
y = 2x-1
y = 2(-2) -1
y = -4-1
y = -5
(-2,-5)
