Answer:
x = -3
Step-by-step explanation:
See steps of solution:
- 5(5x+3) -4(2x-9)=0 ⇒ parenthesis
- 25x + 15 - 8x + 36 = 0
- (25x -8x) + (15 + 36) = 0 ⇒ grouping like terms
- 17x +51 = 0
- 17x = -51 ⇒ subtract 51 from both sides
- x = -51/17 ⇒ divide both sides by 17
- x = -3 ⇒ answer
Answer is -3
Answer:
x = -3
Step-by-step explanation:
5(5x+3) - 4(2x-9) = 0 Multiply out.
5*5x + 5*3 - 4*2x + 36 = 0
25x + 15 - 8x + 36 = 0 Combine like terms.
25x - 8x + 15 + 36 = 0
17x + 51 = 0 Subtract 51 from both sides.
17x = - 51 Divide each side by 17.
17x/17 = -51/17
x = - 3
