-1 Here is why: let x be the number, 4x+7=3 4x=3-7=-4 so 4x=-1 and x is -1
Use algebra.Let x=number of broken eggs. Since there are six times as many unbroken as broken, 6x=number of unbroken eggs.number of broken eggs (x) plus number of unbroken eggs (6x) equals 21x + 6x = 217x = 21 (combine like terms)x = 3 (divide both sides of equation by 7)Since x=number of broken eggs, 3 eggs are broken.Since 6x=number of unbroken eggs, 6*3=18 for 18 unbroken eggs.
3x+30let x = "a number"(x+10) = "a number increased by 10"3(x+10) = "3 times a number increased by 10"Expand: 3x+30
1/3 x+4=121/3 x =12-41/3 x =8x =8x3x =24
36 eggs = 3 dozen
3n + 15 equals 3 times the number n, the answer to which is increased by 15. It can only be evaluated if the value of n is known. The expression can be factorised but that is of marginal help in evaluating it.
Just indicate an addition "+3", attached to whatever you decide to call your "number". For example, if you call the original number "x", the number increased by 3 is "x+3".
15 of 0.2 equals 3.
If there are 12 eggs in 600 grams, therefore there are 3 eggs in 150 grams.
y is increased by 7
