Write down some equations that express what you know.
A = 2*30 + 3x
K = 1*30 + 5x
A+K = 210
Substitute the expression for A in the A+K=210 expression
2*30 +3x + K = 210
Now substitute the expression for for K
2*30 + 3x + 1*30 + 5x = 210
Multiply and combine terms
60 + 3x + 30 + 5x = 210
90 + 8x = 210
Subtract 90 from both sides
8x = 120
Divide both sides by 8
x = 120/8 = 15
