Answer:
x = 7 and y = -2
Given:
x = 5y + 17 _____first equation
2x + 3y = 8 ____second equation
Steps:
2x + 3y = 8
<em>plug in x = 5y + 17 into second equation</em>
<em></em>
2(5y + 17)+3y = 8 [ open the brackets ]
10y + 34 + 3y = 8
10y + 3y = 8 - 34 [ collect and group terms ]
13y = -26 [ divide both sides by 13 ]
y = -2 [ final answer ]
solve for x:
x = 5y + 17
x = 5(-2) + 17
x = 7

Step-by-step explanation:
6x^2 = 3 - 7x
Bringing terms on one side
6x^2 + 7x - 3
Finding factors of 18
6x^2 + 9x - 2x - 3
3x(2x + 3) - 1(2x + 3)
(2x + 3) and (3x - 1) are the factors
