Answer:

See below

Step-by-step explanation:

1) Solve the equation: [4ax - (a + b)](a + b) = 0, where a and b are constants.

if a + b = 0, then x has infinitely many solutions

or

4ax = a + b
x = (a + b)/4a, a≠0

2) Solve the equation m²x + 1 = m(x + 1), where m is a parameter.

m²x + 1 - mx - m = 0
(m²- m)x = m - 1
m(m - 1)x = m - 1
mx = 1
x = 1/m, m≠0

3) Given that the equation a(2x - 1) = 3x - 3 has no solution, find the value of the parameter a.

a(2x - 1) = 3x - 3
2ax - a = 3x - 3
2ax - 3x = a - 3
(2a - 3)x = a - 3
x = (a - 3)/(2a - 3)

<u>The equation has no solution if:</u>

2a - 3 = 0
2a = 3
a = 1.5

Will give BRAINLIEST to correct answer.<br><br> Given that ℓ1 ∥ ℓ2, find x.

lisov135 [29]

X = 38

2x is equal to the angle next to the x + 66 angle because ℓ1 ∥ ℓ2 is parallel so:

2x + x + 66 = 180 -- combine like terms

3x + 66 = 180 -- subtract 66 from both sides

3x = 114 -- divide by 3 on both side

x = 38
