Move the numerals to the right hand side: x = 15 - 7 - 2 ie x = 6
v is -15... -15*2 = -30... -30+11= -19.
5n+15 = 25 5n = 25-15 5n = 10 n = 2
To solve the expression, first calculate the multiplication: 5 times 4 equals 20. Then, substitute that back into the equation: 2 plus 20 minus 7 plus 2. This simplifies to 2 + 20 = 22, and then 22 - 7 = 15, and finally 15 + 2 equals 17. Therefore, the answer is 17.
The answer is 15.
n= -2
-2 plus 5 equals +3
v is -15... -15*2 = -30... -30+11= -19.
5n+15 = 25 5n = 25-15 5n = 10 n = 2
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
