Question

Can anyone help?? Please

Answer 1

3O=12/3   Divide both sides by 3.
/3

O=4

♢+2=5(4)
♢+2=20
    -2  -2      Subtract 2

 ♢=18

 2(4)+18=2∆
8+18=2∆
26=2∆
/2     /2      Divide by 2

∆=13

Answer 2

The circle is worth 4 because it's being multiplied by 3. Then the diamond is 18 and the triangle is -5.
