2 answers:

7 0

<span>1/3(21−3a)=6−a
distribute 1/3 to all factors in the parenthesis
7 - a = 6 - a
add "a" to both sides
7 = 6
This is not true, there are NO solutions to this equation...</span>

alisha [4.7K]

4x + 20 + 2x + 30 = 100
6x + 10 = 100
6x = 90

Which ordered pair (x, y) is a solution to the following system of equations?

Rudik [331]

Answer: (-6, 4)

Step-by-step explanation:

You can use the Elimination method:

- Multiply the the first equation by -3 and the second one by 5.

- Add both equations.

- Solve for y:

$\left \{ {{(-3)(5x+4y=-14(-3)} \atop {5(3x+6y)=6(5)}} \right.\\\\\left \{ {{-15x-12y=42} \atop {15x+30y=30}} \right.\\-------\\18y=72\\y=4$

- Susbtittute y=4 into any of the original equations and solve for x:

$3x+6(4)=6\\3x=6-24\\3x=-18\\x=-6$

Then the ordered pair is:

(-6, 4)
