9x² - 12x + 4

write the equation with two middle terms that multiply to give 36
9x² - 6x - 6x + 4

by factorisation
3x(3x - 2) - 2(3x - 2)

(3x - 2)²

Find the solution of the system of equations 3x+4y=10 and x−y=1. Give the x value followed by the y value, separated by a comma

GREYUIT [131]

Answer:

Solution of the system is (2,1).

Step-by-step explanation:

We are given the following system of equation:

$3x+4y=10\\x - y = 1$

We would use the elimination method to solve the following system of equation.

Multiplying the second equation by 4 and adding the two equation we gwt:

$3x + 4y = 10\\4\times (x-y = 1)\\\Rightarrow 4x - 4y = 4\\\text{Adding equations}\\3x + 4y + (4x-4y) = 10 + 4\\7x = 14\\\Rightarrow x = 2\\\text{Substituting value of x in second equation}\\2 - y = 1\\\Rightarrow y = 1$

Solution of the system is (2,1).
