Answer:
I don't think it's possible to add a number to 20 and then multiply it by 4 and get 3.
Step-by-step explanation:
Answer:
5
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
u-(5)=0
Step by step solution :

Solving a Single Variable Equation:
1.1 Solve : u-5 = 0
Add 5 to both sides of the equation :
u = 5
Answer:
to what?
Step-by-step explanation:
Answer:
2.8+.55x=5 x=4
Step-by-step explanation:
5-2.8=2.2
2.2/.55=4
Y=mx+b
m=slope
b=y intercept
we are given (3,-1)
one solution is x=3 and y=-1 or
when x=3 then y=-1
also slope=2
so
y=2x+b
subsitue 3 for x and -1 for y and solve for b
-1=2(3)+b
-1=6+b
subtract 6
-7=b
y=2x-7 is equation
answer is number 4
