41 + 2y = 0<br> - 4x – 9y= - 28<br> Solve each system by elimination
Iteru [2.4K]

<em><u>Question:</u></em>

4x + 2y = 0

- 4x – 9y= - 28

Solve each system by elimination

<em><u>Answer:</u></em>

The solution is x = -2 and y = 4

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

4x + 2y = 0  ------ eqn 1

-4x – 9y = - 28  ------- eqn 2

We have to solve the system of equations by elimination method

Add eqn 1 and eqn 2

4x + 2y -4x -9y = 0 - 28

0 + 2y - 9y = -28

-7y = -28

Divide both sides by -7

y = 4

<em><u>Substitute y = 4 in eqn 1</u></em>

4x + 2(4) = 0

4x + 8 = 0

4x = -8

Divide both sides by 4

x = -2

Thus the solution is x = -2 and y = 4

snow_tiger [21]
A-1538=1074
a=1538+1074
a=2612




b+718=1074
b=1074-718
b=356



2000-c=1074
c=2000-1074
c=926
