4y - 20.......u need to find a common factor that can go into 4y and 20.....the only common factor is 4. So u can factor that out.....4 goes into 4 one time (but do not forget the y) and 4 goes into 20 five times....4(y - 5)
4(y - 5)...u can also check ur answer by distributing the 4 through the parenthesis and getting 4 * y - 4 * 5 = 4y - 20
784/ 93 = 8.43010752688
93 * <span>8.43010752688 = 784</span>
2x+3y=36
2x=36-3y
y=6
2x=36-3*6
2x=36-18
2x=18
x=18:2
x=9
The only rational root is -2.336071261738453
The other roots are complex (imaginary).
Answer:
Step-by-step explanation:
130+5x=180
130-130+5x=180-130
5x=50
x=10
