What is the answer to this problem
Elden [556K]
I think when you have a fraction like that, you multiply the denominator on both sides obviously by the first step

1 - 3x/5 = -7

Multiply on both sides
1 - 3x/5 * 5 = -7 * 5

and Solve
1 - 3x = -35

Subtract 1 from both sides of the equation
-3x = -36

Divide both sides by -3
-3x / -3 = -36 / -3 (← answer)
x = 12

Hope it helps

Answer:

(b) -m, m + 3

Step-by-step explanation:

x² − 3x − m(m + 3) = 0

x² − 3x = m(m + 3)

x² − 3x + 9/4 = m(m + 3) + 9/4

(x − 3/2)² = m(m + 3) + 9/4

(x − 3/2)² = m² + 3m + 9/4

(x − 3/2)² = (m + 3/2)²

x − 3/2 = ±(m + 3/2)

x − 3/2 = m + 3/2, -m − 3/2

x = m + 3, -m
