Ответ:
-185 = -3r + 20r - 32
-185 + 32 = 17r
r = -153/17
r = -9
Ответ:
-185=-3r+20r-32
-185=17r-32
-153=17r
r=-9
Ответ:
x = 9
Step-by-step explanation:
7x + 3x - 18 = 6(x + 3)
10x - 18 = 6(x + 3) Add like terms
10x - 18 = 6x + 18 Distribute 6 to x and 3
4x - 18 = 18 Subtract 6x to both sides
4x = 36 Add 18 to both sides
x = 9 Divide 4 to both sides
