Answer:
triangle=8, diamond=3, star=11
Explanation:
First you want to start with the equation that only has only shape/variable.
triangle ÷ 2 = 4
multiply both sides by 2 to find that triangle=8.
Now we can plug triangle in another equation.
2+diamond+diamond=triangle
2+diamond+diamond=8
subtract 2 from both sides
diamond+diamond=6
because we know diamond and diamond will be the same, we can divide 6 by 2 to find diamond=3.
Now we can go to the top equation
triangle + diamond + star = 22
8 + 3 + star = 22
11 + star = 22
star = 11
