Question

Q. (1) 13 X + 2 ( 3 + X ) = 60
Q. (2) 1/2 + ( 4 + 2X ) = 10

answer with step -step with explanantion​

Answer 1

Step-by-step explanation:

multiply by +2 inside the brackets

1) 13x+6+2x=60

15x+6=60

15x=54

x=54/15

x=3.6

2)1/2+4+2x=10

1/2+8/2+ 2x=10

9/2=10-2x

9/2-10=-2x

9/2-20/2=-2x

-11/2=-2x

minus gets cancelled

11/2/2=x

11/2×1/2=x

11/4=x
