What is the value of x in this system of equations? Express the answer as a decimal rounded to the nearest tenth.
1 answer:
Answer:
x = 11.2
Step-by-step explanation:
-5x - 12y = -8
5x + 2y = 48
you can combine all like terms from both equations together:
0x-10y=40
simplified:
-10y=40
y=-4
now you plug in the value of y into either equation:
5x+2(-4)=48
simplify
5x-8=48
add 8
5x=56
divide by 5
x=56/5=11.2

Undistribute z
divide both sides by (v-k^5)
Aida did not correctly divide by the common factor to get (4+8).
