Help me pls i don't know

so the a is 4 and the b is 3

that means you have to write 6+1+1 and that equals 8.

your answer is 8

Step-by-step explanation:  in order to get that you have to replace a with 4 and b with 3, if you do you will see that they are simplified to 1. so if you add that the answer is 8. i hope this helped.

you can't solve x because it is 2 linear equation and you only have one equation
