Answer:
x = 68
Step-by-step explanation:
Square both sides of the equation. This gives us:
x - 4 = 64
Then add 4 on both sides. This gives us:
x = 68
Answer:
x=2<br/>y=1
Step-by-step explanation:
\left\{ \begin{array} { l } { 4 x + y = 9 } \\ { 3 x - 2 y = 4 } \end{array} \right.
4x+y=9,3x-2y=4
4x+y=9
4x=-y+9
x=\frac{1}{4}\left(-y+9\right)
x=-\frac{1}{4}y+\frac{9}{4}
3\left(-\frac{1}{4}y+\frac{9}{4}\right)-2y=4
-\frac{3}{4}y+\frac{27}{4}-2y=4
-\frac{11}{4}y+\frac{27}{4}=4
-\frac{11}{4}y=-\frac{11}{4}
y=1
x=\frac{-1+9}{4}
x=2
x=2,y=1
Answer:
for 20 number.
<AEB=142
<BEC=38
<DEC=142
<AED=38
Step-by-step explanation:
or, m<AEB+m<BEC=180(Straight line)
or, 6x-32+2x-20=180
or, 8x-52=180
or, x=29
replacing value of x
m<AEB=6×-32
=6*29-32
=142
m<BEC=2X-20
=2*28-20
=38
m<AED=m<BEC=38(Vertcally opposite angle)
m<DEC=m<AEB=142(Vertically opposite angle)
