7(x - 3) = 4(x + 5)
7x - 21 = 4x + 20
7x - 4x = 20 + 21
3x = 41
x = 41/3
(x - 3) - 2(x + 6) = -5
x - 3 - 2x - 12 = -5
-3x - 15 = -5
-3x = -5 + 15
-3x = 10
x = -10/3
Alright, first blank one is 1/3, then 2/3, then 1, then 1 1/3, then 1 2/3.
Now, shade the 1/3 and 2/3 in blue. Shade the 0, 1 and 2 in red.
Shade the 1 1/3 and 1 2/3 in yellow.
Glad I could help, and good luck!
The value of y = 40.
5x = 40
x = 8
180 = 40 + 40 + (2y + 20)
40 = y
Answer is x = -7 and x = -3
<span> x2 + 10x = -21
</span><span> x2 + 10x + 21 = 0
</span>(x +3) (x +7) = 0
(x +3) = 0
and
(x + 7) = 0
so x = - 3 and x = -7
