You set up an equation with each condition on either side of the equal sign. If I have the problem correct:
(x + 3 + 3)3 = -x + 2. Simplify:
(x + 6)3 = -x + 2
4x + 18 = 2
4x = -16
x = -4
The number that when multiplied by 3, then 4 is subtracted and 2 added and the answer is 16 would be 6 .
((2n + 8)) x 5 = 6n + 12ie 10n + 40 = 6n + 124n = -28n = -7(both equations total -30)
16
The number is 7. 7 x 0.8 = 5.6. 5.6 +14.4 = 20.
5x - 2 = 28Add 2 to each side:5x = 30Divide each side by 5 :x = 6
6
The number that when multiplied by 3, then 4 is subtracted and 2 added and the answer is 16 would be 6 .
6x + 18 = 4 - x 7x + 18 = 4 7x = -14 x = -2
When a natural number is multiplied by 1,000, the product is
4(8+2x)=5x+1132+8x=5x+118x-5×=11-323x=-213 3=-7Therefore the number is -7
((2n + 8)) x 5 = 6n + 12ie 10n + 40 = 6n + 124n = -28n = -7(both equations total -30)
The sum is the total when numbers are added together, the product is the total when they are multiplied.
Let the number be x: 2(2x+4) = 3x+4 4x+8 = 3x+4 4x-3x = 4-8 x = -4
6
16
The number is 7. 7 x 0.8 = 5.6. 5.6 +14.4 = 20.
answer is 3.
