Answer:

(2, 0 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 4 → (1)

3x - 7y = 6 → (2)

Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate x

6x + 9y =  12 → (3)

- 6x + 14y = - 12 → (4)

Add (3) and (4) term by term to eliminate x

0 + 23y = 0

23y = 0

y = 0

Substitute y = 0 into either of the 2 equations and solve for x

Substituting into (1)

2x + 3(0) = 4

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 )

Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.

A coral reef grows
Ksenya-84 [330]
If a coral reef grows at a steady rate every week, then to find how much it grows in 12 weeks, we need to multiply the growth rate by 12 weeks. Also, since we want our answer in centimeters, we can change the growth rate to centimeters. 0.15m = 15cm

15cm * 12 = 180cm

The coral reef will grow 180cm in 12 weeks.
