Solve for E 4/3=6e _ 5/3
pav-90 [236]

Answer:

38.5

Step-by-step explanation:

Lets say, first number = x



Second number = 3x+7



Total = 49




(x)+(3x+7)= 49



4x+7 = 49



4x = 42



x = 42/4



x= 10.5




x= 10.5



3x+7 = 3(10.5)+7 = 38.5




Hope this helps!!

X+4=7 one step equations
nexus9112 [7]
This one is pretty easy. 

x+ 4 = 7
Subtract 4 from both sides so you can isolate the x (Get the x alone) 
x = 7 -4
x = 3
That's your answer. 3.

1) check if they given ordered pairs are solutions to the equation or not.
ziro4ka [17]
Answer: a) Yes
b) No


Explanation: Substitute the values of X and Y from the given points into the equation. I’ll use a) as an example:
Given point: (1,-3)
Equation: 4x-2y=10
Value of X: 1
Value of Y: -3
Substitute X and Y: 4(1)-2(-3)=10
4-(-6)=10
4+6=10 ✔︎

Therefore, the given ordered pair is a proper solution to the equation 4x-2y=10.

*You can use the same method for question b).*
