Question

Solve for x:

139° (10x - 11) / (8x + 15) = 1210

(9x - 17) / (9x - 14) = 153

(7x + 6)

A) x = 10
B) x = 11
C) x = 12
D) x = 13

Answer 1

To solve for x in the equation, use cross-multiplication and combine like terms to isolate x. The value of x is approximately -2.375.

Step-by-step explanation:

To solve the equation: 139° (10x - 11) / (8x + 15) = 1210, we can start by cross-multiplying:

139° (10x - 11) = 1210 (8x + 15)

Next, we can expand and simplify the equation:

1390x - 1529 = 9680x + 18150

Combine like terms:

1390x - 9680x = 18150 + 1529

-8290x = 19679

Divide both sides by -8290:

x = 19679 / -8290

After evaluating the expression, we find that x ≈ -2.375.
