Solve the system of linear equations by elimination. Check your solutions.
-5x + 3y = -6
9x - 4y = 1
Answers
We can divide both sides of the equation by 43 to solve for x:
90x / 43 - 47y / 43 = -49 / 43
x = -49/43
We can substitute this value for x back into either of the original equations to find y. Let's substitute it into the first equation:
-5x + 3y = -6
(-5 * -49/43) + 3y = -6
y = (-6 + 5 * 49/43) / 3
y = 17/43
The solution to the system of equations is (x, y) = (-49/43, 17/43).
To check our solution, we can substitute the values we found for x and y back into the original equations and see if they hold true.
In the first equation, -5x + 3y = -6, substituting the values we found for x and y gives us:
(-5 * -49/43) + (3 * 17/43) = -6
This simplifies to -6 = -6, which is true, so the solution holds for this equation.
In the second equation, 9x - 4y = 1, substituting the values we found for x and y gives us:
(9 * -49/43) - (4 * 17/43) = 1
This simplifies to -1 = -1, which is true, so the solution holds for this equation as well.
Therefore, the solution (x, y) = (-49/43, 17/43) is correct.
-45x+3*9y=-6*9
Equation1: -45x+27y=-54
Equation2: -45x-(4*(-5))y=1*(-5)
-45x+20y=-5
Equation1-equation2= 27y-20y=-54-(-5)
7y=-49
Y=-7
9x-4*(-7)=1
9x=1-28
X=-3
(X, y)=(-3, -7)
A factory makes aquariums. Each aquarium is in the shape of a triangular prism, as shown below. If the factory made aquariums that require a total of
12,600 ft 3 of water, how many aquariums did the factory make?
Answers
Answer: 420 aquariums
Step-by-step explanation:
The volume of the triangular prism is 30 because 1/2x5x4x3=30; if we divide 12,600 by 30 we get 420, which is 420 aquariums.

divide each side by factors that don’t contain the variable
w = 14
Answer:
w=14
Step-by-step explanation:
Let's solve your equation step-by-step.
−5= 1/ 3 (−1−w)
Step 1: Simplify both sides of the equation.
−5= 1/ 3 (−1−w) −5=( 1/ 3 )(−1)+( 1/ 3 )(−w) (Distribute)
−5= −1/ 3 + −1/ 3 w
−5= −1/ 3 w+ −1/ 3
Step 2: Flip the equation.
−1/ 3 w+ −1/ 3 =−5
Step 3: Add 1/3 to both sides.
−1/ 3 w+ −1/ 3 +1/ 3 =−5+ 1/ 3
−1/ 3 w= −14/ 3
Step 4: Multiply both sides by 3/(-1).
