Question

Solve the simultaneous equation:12\\2x-3y=30" alt="4x+3y=-12\\2x-3y=30" align="absmiddle" class="latex-formula">

Answer 1

Answer:

(3, - 8 )

Step-by-step explanation:

4x + 3y = - 12 → (1)

2x - 3y = 30 → (2)

Add (1) and (2) term by term to eliminate y

6x + 0 = 18

6x = 18 ( divide both sides by 6 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (1)

4(3) + 3y = - 12

12 + 3y = - 12 ( subtract 12 from both sides )

3y = - 24 ( divide both sides by 3 )

y = - 8

solution is (3, - 8 )

Answer 2

Steps:

$4x+3y=-12\\2x-3y=30$

---------------------------

$6x+0y=18$

This is the answer you just have to follow the integer rule and combine like variables that all!
