JL = 16+11+28-1

JL = 54

Y=–3x + 6y=9 What is the solution to the system of equations? (–21, 9) (9, –21) (–1, 9) (9, –1)

weqwewe [10]

ANSWER

The solution is $(-1,9)$

EXPLANATION

We want to solve the simultaneous equations

$y=-3x+6---(1)$

and

$y=9--(2)$ .

We substitute equation (2) in to equation (1), to obtain

$9=-3x+6$

This has now become a linear equation in a single variable $x$ .

We solve for x by grouping like terms.

$9-6=-3x$

$3=-3x$

We divide through by negative 3 to get;

$-1=x$ .

Hence, the solution is $(-1,9)$
