5x+10=60 5x=50 5/5=1 50/5=10 So the answer is 10
x2 + 5x = 60 x2 + 5x + 25/4 = 60 + 25 / 4 (x + 5/2)2 = 265/4 x + 5/2 = (265/4)1/2 x = -5/2 ± √265 / 2 x = -(5 ± √265) / 2
-5x + y = -12- 3x + 6y = -12Since both of expressions have a value of -12, their sum is - 24. This is true only whenx = 20/9 and y = -8/9.-5x + y = -12y = 5x - 12- 3x + 6y = -12-3x + 6(5x - 12) = -12-3x + 30x - 72 = -1227x = 60x = 60/27x = 20/9y = 5x - 12y = 5(20/9) - 12y = 100/9 - 12y = (100 - 108)/9y = -8/9

x = 10
9x = 60x = 60/9 = 6 2/3 (or 6.67)
(3)(2)(2)5x=60 12(5x)=60 12(5x)/12=60/12 5x=5 x=1
5x+10=60 5x=50 5/5=1 50/5=10 So the answer is 10
Doesn't have integer roots. Quadratic formula gives roots as 3.71 and -5.38.

x2 + 5x = 60 x2 + 5x + 25/4 = 60 + 25 / 4 (x + 5/2)2 = 265/4 x + 5/2 = (265/4)1/2 x = -5/2 ± √265 / 2 x = -(5 ± √265) / 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.
If you're trying to find the value of x, I've written it step by step here:-5x = 60 + 7xFirst we isolate x. To do this, subtract 7x from both sides.-12x = 60Now we divide both sides by -12.x = -5
-5x2 + 5x + 60 = 0 Remove the common factor of 5 -x2 + x + 12 = 0 Where the coefficient of x2 is negative, it is best to make it positive by multiplying throughout by -1 x2 - x - 12 = 0 The above equation will factorise. (x - 4)(x + 3) = 0 ; therefore x - 4 = 0 when x = 4, or x + 3 = 0 when x = -3 The solutions (roots) of this equation are x = 4 and x = -3.
The answer is y=0 .
60/x = 5 60 = 5x x = 12
