(X-5)(2x+3)=x(2x+3)-5(2x+3)
=x*2x+3*x-5*2x-5*3
= 2x^2+3x-10x-15
=2x^2-7x-15
Terms are: 2x^2. ; -7x. ; -15

Answer:
(4, 5 )
Step-by-step explanation:
Given the 2 equations
y = x + 1 → (1)
x + 2y = 14 → (2)
Substitute y = x + 1 into (2)
x + 2(x + 1) = 14 ← distribute and simplify left side
x + 2x + 2 = 14
3x + 2 = 14 ( subtract 2 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into (1) for corresponding value of y
y = 4 + 1 = 5
Solution is (4, 5 )
