Answer:
6.3
Step-by-step explanation:
i had the same question for school
Answer:
D. Infinite solutions.
Step-by-step explanation:
Since they give us the equation for (y) we just implement that equation in place of (y) in the second equation
15x+3y=27 now becomes
15x+3(-5x+9)=27
Distribute the 3
15x-15x+27=27
15x and -15x cancel out
27=27
Infinite solutions since both sides are exactly equal.
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
Answer:
No
There are infinitely many solutions to the system.
{36x+21y=24312x+7y=81
Multiply the second equation by 3.
3(12x+7y36x+21y=81)=243
Subtract this new equation from the first equation.
36x+21y−(36x+21y0+0=243=243)=0 true
This equation<span> has x terms on both the left and the right. To solve an </span>equation<span> like this, you must first get the variables on the same side of the </span>equal<span> sign. You can subtract 5x on each side of the </span>equal<span> sign, which gives a new </span>equation<span>: x + </span>5<span> = 10. hope this helps</span>
