Whats 5x + 7 =15?



Answers:
The answer is 1.6
You start by putting the numbers together
5x=15-7
this gives 8
so yous tate that 5x=8 and divide 8 by 5 so
x=1.6
X = 1.6
15-7 /5
assuming your asking what X is?
5x = 8
x = 8/5
x = 1.6
An equation (x=8/5)
Twenty twelve?
subtract 7 on both sides and then divide both sides by 5 to find X
5x=15-7=8
x=8/5=1.6
8/5
Here is the working:
5x = 15 - 7
5x = 8
x = 8/5
subtract 7 from both sides
5x = 8
divide both sides by 5
x=1.6
5x+7=15 5x=8 x=8/5=1.6
I would offer that the solution is

5x = 8
x = 8/5 or 1 3/5
5X +7 = 15

5X = 15-7

SO 5X = 8

THEREFORE X = 8/5

I.E. X = 1.6

SOLVED
1.6
5x1.6+7=15
5x+7(-7)=15-7
5x/5=8/5
x=1.6
8/5
1.6
Subtract 7 on both sides:
5x=8

Divide 5 on both sides:
x=8/5

Check:
5(8/5)+7=15
8+7=15
15=15

I hope this helps!
x = 1.6
X =1.6
It is a linear equation. Do you mean it to be solved for x.
5x + 7 = 15

5x - 7 + 7 = 15 - 7


5x=8

x=8/5

x= 1.6

There you go. As you can see it is very straight forward.
1.6
5x + 7 = 15

5x = 15 - 7

5x = 8

x = 8/5
simple

X = 1.6
