5n - 2 = 4n + 1
n = 3
180 inches = ? yards
5 yards
Solve for y:
y - 3x = 13
y = 13 + 3x
abs(x) = 10.2
x = 10.2
x = -10.2
3x+11 = -16
x = -9
2y - 16 = 1/3(y-3)
y = 9
3.2 km = ? cm
320,000 cm
Solve for y:
9x - y = 45
y = 9x - 45
abs(r) = -12
No solution
n + 5n + 7 = 43
n = 6
0.5(6h - 4) = -5h + 1
h = 0.375
(7 gal)/min=(? quarts)/sec
0.47(quarts)/sec
Solve for x:
mx + px = r
x = r/(m + p)
abs(x-4) = 3
x = 7
x = 1
3/2(x - 2) - 5 = 19
x = 18
6m - 6 = 5/6(-6m - 30)
m=-5/2
