5x+6=10

5x=10-6

5x=4

x=4/5

If we substitute the value of x into the second equation


10x+3

10* 4/5+3

8+3=11
Therefore, your solution is 11

Answer: 11

Step by step explanation:

Step 1 : solve the first equation to find the value of x

5x + 6 = 10

5x = 10 – 6

5x = 4

X = 4/5

Step 2 : Substitute the value of x in the second equation

10x + 3 = ?

10 ( 4/5) + 3

= 40 / 5 + 3

= 40 + 15 /5

= 55 / 5

= 11
