Set up the proportion. That's what similar gives you the right to do.
(12 + 3) / 4x = 12 / (3x + 1) Cross multiply
15 * (3x + 1) = 12 * 4x Remove the brackets
45x + 15 = 48x Subtract 45x from both sides.
15 = 48x - 45x
15 = 3x
x = 5

Answer: 1.5
Step-by-step explanation: Given:
A=1/10×5 + 11²
B= 5 - 11²
If c = A + B
c = ( 1/10×5 +11²) + ( 5 - 11² )
= ( 5/10 + 121) + ( 5 - 121)
= ( 121.5) + ( -120)
= 121.5 - 120
= 1.5
