Answer:
x=4 y=8
Step-by-step explanation:
y=2x
y=12-x
Substituiting y value from first equation into second equation.
2x=12-x
3x=12
x=4
y=2(4)=8
y=12-4=8
Answer:
90000
Step-by-step explanation:
9 x 10 (to the power of 4)
move the zeros to the right side four time, because the power of 4 is positive.
X=2 Y=-4.5 I got this by substituting the value of x into the equation 3(2y+7)-2y=3 and solving.
X should be equal to four. You divide 35 by 9 to get the answer (x=4)
Answer:
(9+1/6)+(1.8+2 3/5)
55/6 + (9/5 + 13/5)
55/6 + 22/5
407/30 = 13 17/30 = 13.56
