Assuming this is a system of equations, here is how to find x.

2x + 3y = 45
x + y = 10

Multiply x + y = 10 by 2 so you are able to use the elimination method.

2x + 3y = 45
2x + 2y = 20

Subtract.

y = 25

Now that we've found y, we can plug it in to find x.

x + 25 = 10

Subtract 25 from both sides.

x = -15

What is the value of x in this equation? Enter your answer in the box.

katrin [286]

Answer:

Step-by-step explanation:

(2.4×10³)×(3×10^x)=7.2×10^9

(3x10^x)=(7.2×10^9)/(2.4×10^3)

3×10^x=3×10^6

10^x=10^6

*when bases are same ,powers are equated*

thus x=6
