Answer:
y= 2x-1/2 is x=.5 y + .25
2x-3y=4 is x = 1.5y + 2
Step-by-step explanation:
pretty sure thats it
3p - 2p - 5
collect like terms
(3-2)p - 5
calculate
1p - 5
the coefficient of 1 doesnt have to be writtent
Answer: p - 5
Answer:
B - 11 > (w - 4)²
C - y < 3⁴
D - 5 + 9 < 5 · 9
are your correct answers
Step-by-step explanation:
x² - 5x + 6 and z + 11 / 2z - 1 are equalities phrases and rest of them will be inequalities.

Answer:
x = 3 and y = 2
or
(3,2)
Step-by-step explanation:
first equation (LCM = 3 x 4 x 5 = 60)
(x+2)/5 - (9-x)/3 = (y - 6)/4
12(x+2) - 20(9-x) = 15(y - 6)
12x + 24 - 180 + 20x = 15y - 90
32x - 15y = -90 - 24 + 180
32x - 15y = 66
second equation:
8(x + 2) - (2x + y) = 2(x + 13)
8x + 16 - 2x - y = 2x + 26
6x - y + 16 = 2x + 26
4x - y = 10
Now you have 2 equations:
4x - y = 10 ---> y = 4x - 10
32x - 15y = 66
Substitute y = 4x - 10 into 32x - 15y = 66
32x - 15(4x - 10) = 66
32x - 60x + 150 = 66
-28x = -84
x = 3
y = 4(3) - 10
y = 12 - 10
y = 2
Solutions: x = 3 and y = 2
