Answer:
(7,9)
Step-by-step explanation:
7x - 8y = -23
7x - 7y = -14
Solve the equation for 7x
7x - 8y = -23
7x = -14 + 7y
Substitute the given value of 7x into the equation 7x - 8y = -23
-14 + 7y - 8y = -23
solve the equation for y
y = 9
substitute the given value of y into the equation 7x = -14 + 7y
7x = -14 + 7(9)
solve the equation for x
x = 7

Answer:
285 Miles in 5 Hours
Step-by-step explanation:
342/ 6 = 57
57 x 5 = 285
Answer:
see explanation
Step-by-step explanation:
Given
2x² + x - 1 = 2 ( subtract 2 from both sides )
2x² + x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 3 = - 6 and sum = + 1
The factors are - 2 and + 3
Use these factors to split the x- term
2x² - 2x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x + 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -
