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

Answer:
f(-1) = 3
Step-by-step explanation:
See the graph shown in the attached file with the given question.
The graph passes through (0.5,0) point on the X-axis and (0,1) point on the Y-axis.
So, the length of the X-intercept is 0.5 and that of Y-intercept is 1.
Hence, the equation of the straight line graph is
{Using the intercept form}
⇒ 2x + y = 1 ....... (1)
Now, y = f(x) = 1 - 2x
Hence, f(-1) = 1 - 2 ( - 1 ) = 3 (Answer)
