10x+3y=19
y=2x+5

10x+3(2x+5)=19
x=1/4

y=2*1/4+5
y=11/2

(x,y)= (1/4,11/2)

10*1/4+3*11/2=19
11/2=2*1/4+5

19=19
5.5=5.5

The answer is (x,y)=(1/4,11/2)

<h3>What are algebraic expressions?</h3>

Algebraic expressions are expressions that contains variables, constants, factors and coefficients.

They are also made up of arithmetic operations such as addition, subtraction, multiplication, division, etc.

From the information given, we have;

(- x^2 - 5x ) - ( 6x^2 + 5x)

expand the bracket

-x^2 - 5x - 6x^2 - 5x

collect like terms

-7x^2 - 11x

Thus, the expression is simplified to give -7x^2 - 11x
