-0.5

Y=15/(2c+2x)

If: 20x+5y = 15 Then: y = -4x+3

8x = 2x + 15 6x = 15 x = 15/6 = 2.5

15+b = 23 Subtract 15 from both sides b = 8

5x+y=-7 3x+y=15 8=D

15 + n = 24 (subtract 15 from both sides) n = 9

(0,7)

solve -3x-3y=-15

It equals 285

8x+39 = 2x-15 6x = -54 x = -9

v is -15... -15*2 = -30... -30+11= -19.

4m+15=8m-5 or,4m=20 or,m=5

80 = 3y + 2y + 4 + 1 75 = 5y 15 = y y = 15

In math problems without punctuation such as brackets, the standard convention in to solve from left to right. Therefore, you would solve the problem 15-3 times 4 plus nine like by three actions. 15-3 equals 12; 12 times 4 equals 48; 48 plus 9 equals 57.

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.

x = -1 Since -3(-1) + 15 = 18

3x+5=20 3x=15 x=5

-3x + 5 = 20 -3x = 15 x = -5

The best plan for that particular equation would be to first subtract 15 from each side, and then apply the quadratic formula.

5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
