The system of equations 5x - 4y = -3 3x + 2y = 7 has the same solution as the system
(1) 5x - 4y = -3 6x + 4y = 7
(2) 5x - 4y = -3 6x + 2y = 14
(3) 5x - 4y = -3 6x + 4y = 14
(4) 5x - 4y = -3 9x + 6y = 14
What is (3) 5x - 4y = -3 6x + 4y = 14

(1) 0.27 (2) 200
(3) 0.73 (4) 146
What is (1) 0.27
In order to eliminate the y from the system of equations,
6x + 4y = 22
3x + 12y = 21
you could
(1) Multiply both sides of the first equation by -2
(2) Multiply both sides of the second equation by -3
(3) Multiply both sides of the first equation by -3
(4) Multiply both sides of the second equation by (1/2)
What is (3) Multiply both sides of the first equation by -3
The height of a projectile thrown in the air can be modeled with the equation h= -16t^2 + 48t + 160, where t is the number of seconds. At 1.5 seconds, how high will the projectile reach?
