Find the value of y in the equation 48=y*8 |
|
Answer» Answer: Step 1 - 8x-2y=48 Step 2 - if I DIVIDE by 2 in the Step - 1 .its MAKE the equation more simple for calculation - 8x/2–2y/2 = 48/2 Same equation but simple format then-new format Equation —-> 4x-y=24 Step 3 - they gave the above question y =4 ( it means you PUT the value of y =4 in new format equation) Step 4 - Next step put the value of y=4 in new format equation 4x-y=24 ->4x -4 = 24 —put value (y=4) → 4x = 24 +4 → 4 x = 28 → x =28/4 ( well we know 4 *7 = 28 ) → x =7 ( answer ) how to check the answer its more easy and its always work when you want to check your answer .it’s correct or not. Check - well we know it y=4 and my answer x =7 so it's very easy you put the X and Y value in your step 1 - → 8x-2y=48 — (put value x= 7 (that's my answer ) and y =4 ( which already provide you ) → 8 *7 -2 * 4 = 48 →56–8=48 →48 = 48 ( NICELY we done on it and prove on it x= 7 and y =4 ( don’t confuse y value already given) |
