Question

x+2=7
x-7=4
5x=7
which of theese equations can be solved to find the value of x

Answer 1

Answer:

In Equation

1) x+2=7

2) x-7=4

we can find "x" value

Step-by-step explanation:

1)

x+2=7

x=7-2

x=5

2)

x-7=2

x=2+7

x=9

But in third equation we can't find the value of "x".

Because: 5x=7

x=7÷5

x=1.4

We are getting "x" in decimal form...

So we can't get "x" in 3rd equation
