x=9
Step-by-step explanation:
Equation: 5.60x=50.40
Solve: 5.60x=50.40
Divide both sides by 5.60 ( 5.60x/5.60 ) and ( 50.40/5.60 )
is good by his guan yes is help to me
x+ 3/2y= 15
8x+12y=120
To put the equation into standard form, the leading coefficient has to be 1. So, divide the whole equation by 8.
