Answer: 1.72.......

Step-by-step explanation: 4.3x + 7 + 5x = 16 + 7

=> 7 + (5x + 4.3x) = 16 + 7

7 + 9.3x = 23

9.3x = 23 - 7 [ 7 becomes -7 when transferred to RHS]

9.3x = 16

x = 16 /9.3 [ 9.3 becomes 1/9.3 when transferred to RHS]

x = 1.72......

Hope it helped u,

pls mark as the brainliest
