Elimination<br>3x +2y=9<br>3x ty=0<br>1

Answer:

$y = 9$

$x = -3$

Step-by-step explanation:

Given

$3x + 2y = 9$

$3x + y = 0$

Required

Solve by elimination

To do this, we subtract both equations (to eliminate x)

$3x + 2y = 9$

- $3x + y = 0$

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

$3x - 3x + 2y - y = 9-0$

$y = 9$

Substitute $y = 9$ in $3x + y = 0$

$3x + 9 = 0$

Solve for 3x

$3x =- 9$

Solve for x

$x = -9/3$

$x = -3$

PolarNik [594]

Answer: 48

Step-by-step explanation:

l = w + 7

2w + 2l = 178

2w + 2(w + 7) = 178

2w + 2w + 14 = 178

4w = 164

w = 41

l = w + 7

l = 41 + 7

l = 48
