[tex]5x+6=10[/tex]
[tex]5x=10-6[/tex]
[tex]5x=4[/tex]
[tex]x=4/5[/tex]

If we substitute the value of x into the second equation

[tex]10x+3[/tex]
[tex]10\times 4/5+3[/tex]
[tex]8+3=11[/tex]
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
