Answer:
3/10
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
<h2>Simplifying expressions:</h2>
5x - 7 - 5(7x - 12) + 7 = 0
Distribute (-5) to each term of (7x - 12)
5x - 7 + 7x*(-5) + (-12)*(-5) + 7 = 0
5x - 7 - 35x + 60 + 7 = 0
5x - 35x - 7 + 60 +7 = 0
Combine like terms.
-30x + 60 = 0
Subtract 60 from both sides
-30x = -60
Divide both sides by (-30)
x = (-60)/(-30)
x = 2
Ans: 5*-3=-15
