5x + 3 = -12 5x =-12-3 =-15 x = -3
5x+3=8 is a simple equation, and I can tell you off the top of my head the answer is 1. Here's how to work it: 5x+3=8 5x+3(-3)=8(-3) 5x=5 5x(/5)=5(/5) x=1
5x + 3 = 18 Subtract 3 from both sides: 5x = 15 Divide by 5: x = 3.
Factors are (5x +1)(x - 3)
Answer is D.73
If x = -7 and y = -3 then 5(-7) -2(-3) = -29
5x-3 would be the answer.
3 + 5x is the simplest expression of this problem.
5x plus 3 does equal 3 plus 5x; commutative law.
25x2+30x+9 25*9=225 15*15=225 15+15=3025x2+15x+15x+9[5*5xx 3*5x] [3*5x 3*3]5x(5x+3)+3(5x+3)(5x+3)(5x+3)Answer: (5x+3)2
5x-5 = -3 5x = -3+5 5x = 2 x = 2/5
5x+3 = -17 5x = -17-3 5x = -20 x = -4
5x-3 = 37 5x = 37+3 5x = 40 x = 8
5x² - 18x + 9 = (5x² - 15x) - (3x - 9) = 5x(x - 3) - 3(x - 3) = (5x - 3)(x - 3).
steps: 3(5x-7) =(3)(5x-7) =(3)(5x)+(3)(-7) answer: 15x-21
5x + 3 = -12 5x =-12-3 =-15 x = -3
