Which solution is the best estimate to the system of equations? {y=14x−2y=−2x+3 (2.2, −1.4) (0, 3) (0, −2) (1.5, 0) a system of two linear equations. two lines graphed on a coordinate plane with x and y axis ranging from negative 5 to 5. one line passes through the points begin ordered pair 0 comma 3 end ordered pair and begin ordered pair 3 comma negative 3 end ordered pair. the other line passes through the points begin ordered pair 0 comma negative 2 end ordered pair and begin ordered pair 4 comma negative 1 end ordered pair.

The best estimate solution to the system of equations is (0, 3)

Step-by-step explanation:

we have

y=14x-2 > equation A

y=-2x+3 > equation B

Solve the system by elimination

Multiply the equation B by 7 both sides

(7)y=(7)(-2x+3)

7y=-14x+21 > equation C

Adds equation A and equation C

y=14x-2

7y=-14x+21

y+7y=-2+21

8y=19

y=19/8

Find the value of x

y=14x-2

19/8=14x-2

19=112x-16

112x=19+16

112x=35

x=35/112

so

The solution is the point (35/112,19/8)

Convert to decimal number

(0.3125,2.375)

therefore

The best estimate solution to the system of equations is (0, 3)

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
