○ + ○ + ○= 30
○ + ¤¤ + ¤¤= 18
¤¤ - ☆☆= 2
☆ + ○ × ¤= ?
○ =10
¤¤ = 4 so ¤ =2
☆☆= 2 so ☆ = 1
○ + ○ + ○ = 10 + 10 + 10 = 30 ...correct
○ + ¤¤ + ¤¤ = 10 + 4 + 4 = 18 ...correct
¤¤ - ☆☆ = 4 - 2 = 2 ...correct
☆ + ○ × ¤= 1 + 10 x 2 = 21

9x, could i have brainliest if possible thanks!
So the change in between terms is 5 so you would put 5x, then for the first term, which is 2, 5*1(x)(because it's first term) then the difference between 5-2(because it's the 2nd term) So you would plug 100 in for x so 5(100)-3=497. Hope this helped!
